The following is a non-exhaustive list of kins that men often have that, in my humble opinion are red flags. Men that kin these characters may be fixable, but they may also just need time to figure themselves out.
This list will be updated over time as I come across more.
Wheatly (Portal 2)
He sees himself as an under-dog, and wants to conquer, but has some awareness that he just makes everything worse. This can lead to a self-pitying downward cycle as he tries to overcome his own perceived failure.
Sweeney Todd (Sweeney Todd: The Demon Barber of Fleet Street)
Again, he sees himself as an under-dog, but also feels that he has consistently been wronged, and now the only recourse is to hurt anyone he can. Is jaded and thinks that since “no one cares” that he was hurt, he shouldn’t feel any remorse for his own actions.
Patrick Bateman (American Psycho)
Intense case of main character syndrome. Feels little to no sympathy for others, and sees no problem with using and hurting anyone and everyone to get what he wants. May or may not be an actual psychopath, but definitely wishes he was.
Dr. Horrible (Dr. Horrible's Sing-Along Blog)
Yet another under-dog. Thinks that only he can see the atrocities of the world, and that everyone else is willfully blind to the “facts”. Furthermore, this person has delusions of grandeur, and thinks that he, and he alone, has the gumption to fix the wrongs in society, even if he has to do it by force.
Rick Sanchez (Rick & Morty)
Believes himself to be a lone genius. Jaded and narcissistic. Thinks that everyone else is beneath him, and they just don’t “get” him. Willingly refuses to “lower” himself to enjoy things others around him enjoy. Knowingly pushes people away from him with his behavior, and then uses people not liking him to further justify pushing people away.
