Oh man, twin. You had to spring this one on me, huh? XD I could be writing this for hours considering how much I think about this muse and his actions.
I think Loki is very human in the sense he has layers. He’s constantly evolving, and he has more faults than he has perfections—faults that he does not always acknowledge, nor does he try to correct them (something that only aids in his descent into villainy imo). In Thor, we’re introduced to a seemingly very meek and intelligent individual with a penchant for mischief. These things are shown in the way he articulates himself. His expressions are more docile, his words more smooth and honeyed. He plays the part of a ‘angel on your shoulder’ quite well when he wants to—such as when he tried to ‘talk Thor out of’ going to Jotunheim.Jotunheim, of course, is what changes everything and spurs (what I believe as my head canon) a very big amount of self-hatred inside of Loki for what he is. He doesn’t want to be the monster, of course, because who would want to be a monster? So I think he goes into a heavy dose of denial up until the confrontation with Odin. As for Loki’s meek and ‘good little brother’ behavior, well… We learn this is far from the truth later on, of course, but something I do want to say is I don’t believe Loki intended for Thor to be banished. I think such a punishment from their father to Thor—the one he saw as the favored, the sun to the shade he’d been ‘forced’ to become—seemed unthinkable to Loki. Don’t get me wrong—Loki knowingly got Thor into trouble. It just seems to me he didn’t realize just how much trouble he was getting them all into. He’s very defensive from the get-go about this and many other things. He doesn’t like to accept blame (though he dishes it out freely and without discrimination). I think jealousy towards Thor has always been there, but I don’t doubt for a single moment there was also love. I think Loki has always loved his family. Even post-Thor 2, I think that love is there. Love isn’t something so fragile that lies disintegrates it wholly. Does it get damaged? Yes. Does one want to keep love when the source of it has caused perceived pain? Of course not. That doesn’t mean it leaves though. You can love the people who hurt you, the proof of that is Thor himself, and Frigga, and even Odin (and none of you tell me Odin doesn‘t love Loki; he raised the boy as his son and frankly, after the shit Loki did? Loki deserved every bit of harsh tonguelashing Odin put on him. He‘s a king before a father because he has to be, and Loki has hurt him too and I think Odin carries his own guilt and pain regarding what happened to him ok). Loki—He claims to hate them, but his actions always seem so approval seeking to me. He’s like a desperate child vying to be the favorite, or one denied a treat they asked for. He feels like he’s being deprived of things he’s entitled to. I think there was a chance still for Loki before he fell from the bifrost, but the moment he fell into the wormhole (and as Hiddles has said, it’s the equivalent of going through the seven layers of Hell) he was doomed to be what he was in The Avengers: desperate, hectic, unhinged, and unapologetic. Gone was the soft Loki Odinson you saw in Thor, in came Loki Laufeyson, who in his scramble to prove he was better—became even more similar to the very thing he detested.Thus is his folly, I guess.Over all, I think he digs his own grave. I think he does things carelessly, no matter how much planning goes into things, and as a result he only realizes the wrong he has done until it’s too late—until he feels the consequences of what he does and says. He doomed himself.
