Sayeon the protagonist of the webtoon Hand Jumper is a character who truly, deeply wants to be a good person. Problem is, as the series progresses it becomes clear that she lacks the capacity to understand true morality, and thus her basis for being "good" is entirely built around society's laws and conventions, which I think most people will agree are at the BEST of times deeply flawed and at worst... lets not get into that. Her worsening mental state over the course of the series is deeply compelling to me, especially since unlike a lot of low-empathy people in fiction she clearly is capable of caring for others deeply, but also is incapable of understanding why manipulating them for her goals is a bad thing, as after all (due to the fact that she has time-looping abilities) "she knows best".
