Note: All of this is partly based on information that I DONāT KNOW IF ITāS STILL CANON, along with my own speculation. If you can correct or add more hypotheses, please do so. I donāt want this fandom to ever fade away.
I remember someone asking whether Mordecai really had a bullet (or fragment) in his head and whether that was the reason for his āpeculiar personality.ā In response, T.B. mentioned New York. From what I understood, it was the result of something that happened in that place (though I donāt know if thatās still canon). Some people speculated that it was due to a head injury in his childhood, his teenage years, or an injury he got while working for bookmakers.
I think Bobby mentions that as an attempt to explain Mordecaiās unusual personality (whether it was his own hypothesis or one from the people who told him the story about the bullet in the head). After all, at that time the concept of neurodivergence didnāt exist, and the idea of trauma as a source of mental distress expressed through behavior was only just beginning to be explored. And itās those two factors, neurodivergence and the post-trauma from what he experienced in New York, that in my view are the real reasons behind Mordecaiās current personality, rather than a bullet.
The trauma, for its part, is said to arise from EVERYTHING that happened in New York:
To begin with, from the little that is known about Mordecai, his neurodivergence was evident in childhood (though not within his historical context, of course). Beyond his āintellectual quotient,ā he showed focused curiosity and difficulty understanding emotions, double meanings, and other aspects that have been explored in many analyses of the character. In other words, he already had a personality that others might consider ādifficult,ā often expressed through his sharp, biting criticism and a certain degree of arrogance. We constantly see him trying to isolate himself in his own interests, yet failing in the face of his sistersā teasing. Itās likely that this was one of the secondary reasons why he later sought his own space outside the home.
It is also mentioned that as a child he used to laugh and cry, which shows the existence of emotions that he neither controlled nor understood, but also did not repress. Later, when he attempts to express them as a social formality, Atlas corrects him and forbids him from doing it again, likely because by that point he is no longer able to do it naturally. It can therefore be inferred that this is a case of natural behavior versus behavior altered by a series of traumas.
It has been mentioned, for example, that his obsession with cleanliness comes from constant paranoia about contracting infections or diseases, perhaps even from knowing that he didnāt have the resources to obtain effective treatment or that such treatment might not even exist. This would put a developing mind in a constant state of alert, turning that fear into an obsession in order to survive. After all, cleanliness and order (even symmetry as a form of balance) are associated with control, which in Mordecaiās mind could translate: into controlling variables that reduce or eliminate danger, noise, or anxiety, thereby achieving a sense of safety and, consequently, survival. You reduce everything to the essential to prevent the system from collapsing, and he applies this to his whole life, or at least thatās what he wants to believe. [In other words, another adaptation to trauma.]
It is mentioned that after the death of Isaac, Mordecai takes on greater responsibility. I imagine that beyond his affection for his family and their economic needs, he may have been influenced by the idea that the man of the household had to be the provider, along with the fact that he was the eldest son. Letās remember that within his own religious community, certain attitudes are expected of a son after the fatherās death. This pushes him to enter working life at a young age, with outstanding abilities, yes, but without reliable guidance. This is later confirmed when problems grow once Mordecai begins working, where a lack of opportunitiesāperhaps due to age, background, religion, etc.ālimits his possibilities, and jobs with adequate pay donāt come from legal places. Perhaps in this sense he is recruited by organized crime both for his special skills and simply because he is a young mind that is easy to manipulate, shape, and use (something that Atlas repeats or āoptimizes,ā but in a more āheroicā way). In this sense, necessity itself is what initially pushes him, step by step, down into a life of violence and death:
(+) >> Poverty >> Lack of opportunities he perceives as sufficient >> Recruitment into the criminal world >> Likely negative influence on an adolescent mind whose morality and ethics are still forming >> Normalization of criminal behavior >> (+)
Once inside that world, he keeps descending. Itās mentioned that after a betrayal that harmed his family financially, he extorts, then kills, and then impersonates the person who betrayed him. Perhaps in Mordecaiās mind this was ājustice,ā not only because his family was affected but because he himself had been betrayed. A double offense. A person who, in his view, had stepped outside the structure of hierarchy and roles he had built in his mind was probably worth nothing anymore. Maybe this is how he rationalizes his first killing, to keep himself from collapsing after that first severe trauma: committing murder. -(Here there may be a notable contrast with Atlas. Whether or not Atlas took advantage of him, he gives Mordecai a new structure and doesnāt break it by betraying him ā at least not in a way Mordecai perceives. He offers economic stability, structure, usefulness, a sense of belonging in general, which is why Mordecai clings to Atlasās memory and seeks explanation or revenge against those who took that refuge away from him.)
Later, weāre told that after impersonating the traitor, Mordecai starts embezzling funds from a larger criminal network, initially just to recover the money he lost, but in what was probably growing arrogance, he steals more and more. Once he has taken over the position, he descends even further. Swindling, extorting, killing, impersonating are no longer enough. He has already stepped down several rungs, so itās not hard to imagine that in his mind stealing from bigger criminals is the lesser evil among the series of crimes he had already committed. But he is discovered and almost killed for it. Here lies another trauma, one where not only he but also his family faced danger. This leads to increased isolation and distrust, and to his desire to go unnoticed in the streets. I believe it was even mentioned that he would change apartments periodically. He no longer allows himself to have a permanent home, with everything that symbolizes. In short, and in a rough sense, we can say that Mordecai seems to be more the result of a series of misfortunes and traumas that further intensified "his already difficult personality".
Does this mean heās lost?
Heās certainly sunk very deep, but throughout the story we see him preserve some degree of affection for others in his own way. Whether itās when he avoids shooting Ivy, when he injures Viktorās knee so they wonāt have to fight, or even when Serafine tells him he looks like a traitor and Mordecai replies that she doesnāt understand anything about that, perhaps indicating she has no idea how loyal he can be. After all, if he has one defining trait, itās that he doesnāt seem to betray his colleagues unless they give him a reason to; preserving the structure is his closest form of affection.
The question is: under what circumstances will he continue to maintain or lose that affection toward his former colleagues? Whom does "he consider his current friendsā? Will his desire for revenge over what happened to Atlas prove even stronger? Could he become a traitor? That last part seems to be wearing away at his mind little by little. After all, he let a target go in order to obtain more information, and there will be consequences.
