I will willingly admit that thomas isn't really the nicest person to most people.
However as a queer person who until recently was in the closed, I understand. Having to hide such a large part of yourself from the people around you is so difficult, and it can make you a really bitter person, and I'm living in a time/place where being me is legal, thomas wasn't.
He had to live with the fear of being discovered while constantly having to hide his true feelings, all whilst being constantly told he's disgusting, wrong and lives in a repulsive world, to quote Carson. So maybe he was cruel to everyone else, especially in the earlier seasons, but really cruelest to himself.
And incase anyone says, yes I know he's fictional, but there were so many thousands of people in a similar situation that need to be remembered.
