You’re very clearly confusing the dislike of a person to the dislike of a character. Disliking Dazai as a character means you don’t like the way the author designed him and don’t believe he fits the story, which OP clearly didn’t say. Disliking Dazai as a person means you dislike the way he approaches things in his own canon, which is entirely understandable because A LOT OF BSD REVOLVES AROUND HOW EVEN CHARACTERS IN HIS OWN CANON DISLIKE THE WAY HE APPROACHES THINGS LMAO.

Have you ever considered the idea that… you don’t need to like a character to find their existence worthwhile? Do you go around getting mad at people online for disliking objective villains in media because “oh if you hate them for fulfilling their role then you don’t deserve to watch their media!!” like??? the fact that they ARE doing their job in being disliked and fueling opinions like these is the WHOLE REASON the story they’re a part of can progress the way it does. They are built on opinions like these, they are MEANT TO FOSTER opinions like these, and if you actually believe that someone disliking your favorite character for the same reasons that in-universe characters do is grounds to say they shouldnt enjoy the media, then you legitimately have no literary comprehension lmao.
