Both danganronpa and even rain code have this underlying but incredibly persisting theme of the cognitive dissonance between one's personality vs their own nature that I can't help but think about a lot.
In my head I tend to call it the "Leon paradox" because he's the first and most obvious character I think of in regards to this, though he's far from being the only one. Despite being an effortlessly talented baseball prodigy, he dislikes doing it and his actual passion is becoming a musician. However, he's pigeonholed into doing something he doesn't enjoy simply because he's good at it and it's a means to an end since it's his only way of getting anywhere.
This gets expanded in dr2. Imposter's dissatisfaction with having to always be someone else. Akane not caring about being a gymnast much at all aside from the perks it gets her. Nagito's disdain for his luck talent that brings him constant misery while also acknowledging that it's the one thing about himself that he can count on the most.
It even becomes a focal point with Hajime, who did everything to fight his nature of lacking a talent. However, Chiaki points out that it's the fact that he has no specific talent that gives him more freedom than any of the ultimates that he admires. Turned out, gaining every talent put Hajime into his own prison, and it's his loss of personality that made him essentially useless.
Even in V3 you have Kaede who actually loves her talent so much that she feels like it's an obsession that affects her ability to socialize normally. Kokichi also seems to have brief moments where he acknowledges that his talent is a huge barrier to being able to actually connect with people and causes his loneliness, but decides that it's a compulsion that's too troublesome to change so he just accepts it.
Shuichi sticks out to me when it comes to this theme. He's extremely good at detective work and will often do it on impulse regardless of reward. However, even just stumbling on his first murder case and solving it before the police could even touch it, he could not cope with the results of the person he'd affected. His emotional sensitivity traumatized him into being avoidant, even using a hat as a literal blinder. He was prepared to die in the first trial in fear of revealing the truth. His compulsion to do detective work even kind of ruined Kokichi and Kaito's plot in ch5, as he got so ahead of himself with revealing the truth that just kind of blurted everything out before realizing that he shouldn't have. His compulsion with detective work even seems to make him comparatively calmer and more focused during investigations than the other protagonists, despite easily being the emotionally weakest-willed out of all of them. He repeatedly keeps falling back into his talent despite the emotional toll it has on him because he just can't help himself. He kind of acts as an example of one of the reasons why Kyoko was trained to be emotionally detached.
Jin actually is very much like Shuichi. He tries to actively avoid detective work because he despises the emotional detachment required for it. You wouldn't even know that he's actually really good at it, but you see glimpses into his skill in the novels where he'll end up figuring things out before even Kyoko does on more than one occasion. I can talk a lot about Jin, but I do get the feeling that one of the reasons why he works at Hope's Peak is because he knew more about what would end up happening there than he let on. He probably could have gotten quite a few things done if he wasn't so insistent on fighting his own nature as a detective.
Very honorable mention to Yui, who turned down an invitation to Hope's Peak for her high-jumping talent in order to pursue her passion as a very mid detective. She might've even lived if she went to Hope's Peak because I'm pretty sure she would've graduated by the time of the tragedy, but at least she died in the most based way possible by rejecting them.
And of course, Junko is a prime example of the detrimental effect of talent. Because of her analytical abilities, she can practically guess everything that's going to happen. Her obsession with despair is a desperate attempt at being mentally stimulated in a society that has let the status quo stagnate to such a critical degree that it's the reason why the very concept of talent had been rotted to this point. Sorry to Kodaka, who has repeatedly said that Junko is meant to be a truly evil villain with no motivation, but he did kind of accidentally give her a motivation in dr0 where we're shown for a fact that without her memories and ability to analyze, she's relatively normal and tame. That is her nature, just a kind of weird girl who wants to be a tradwife and go grow corn somewhere. However, I think it can be argued that what is meant by "pure evil with no motivation" is that she doesn't have any sort of tangible tragic backstory. You can even say it's not her analyst ability alone that caused her madness, since there's plenty of normal non-world-ending analysts. It may simply be that her personality happened to mix terribly with her talent, and that's the nature of what makes her pure evil, because both of those aspects of her are part of her nature that she can not (nor does she even want to) control despite the misery it causes her. She simply learned to love the misery.
Makoto himself is very clear about being bitter about his luck. For the most part, what's apparent to him is that it causes him constant trouble and the good that it actually does for him is so subtle and disjointed that he doesn't even realize it's his luck. However, I think what makes him different from people like Nagito or Junko is his personality. He doesn't obsess like they do, and his optimism makes him bounce back easily. I think his luck even feeds into his personality and, inverse to Junko, it's the unpredictability of his luck that makes him hopeful and optimistic. Since he never knows what's going to happen to him, he had to develop a way to roll with the punches.
The aspect of personality vs ability also carries over to rain code. The master detectives are people who have innate psychic abilities that are seemingly based on their nature, and then it gets refined and specialized based on their personality. Not only does their personality help to refine these powers, but you see that their personalities and abilities often have detrimental impacts on each other.
Halara can't see living things in their postcognition because they aren't good at looking at people. Pucci's ability makes her hearing so sensitive that it's at least partially caused her emotional detachment. Melami not only likes fashion so much that she must wear the clothes of someone to use her power, but she also has to actually like the clothes too. Vivia is constantly fatigued and has depressive tendencies due his tenuous attachment to his spirit.
Former Number One/Makoto are a great example of this sort of destructive feedback loop of cognitive dissonance. You can infer that their empathy and obsession with helping people is what gives them the ability to use coalescence and share anyone's abilities, yet it's the fact that they can do anything that makes them feel like they must do everything. Ironically, the fact that they've convinced themselves that they must do everything makes their ability essentially useless because they end up only working alone. As a result, Former Number One became detached with every emotion except for his obsession, and it's what caused Makoto to ultimately spiral.
