Jason

I think it is safe to say that when it comes to quality of character, Jason himself is a pretty terrible one overall. As a child and now as an adult, Jason constantly found pleasure in annoying and bullying others, all with a bloated sense of superiority to those around him. An example comes in the way of Jason blaming Caddy for him not getting the bank position that Herbert Head had promised him, despite Caddy being the reason he was even recommended to begin with. And Benjy's castration and eventual send-off to the insane asylum is primarily due to Jason's actions. But, oddly enough, both Benjy and Jason do share a common character trait: they are only able to see actions in terms of them effecting them each personally. None has any concern for others, but in Benjy's case, it is a little more understandable as he does have a disability. And finally, Jason is the only child that received his mother's love, despite being the only one that never wanted it nor reciprocated it. We truly see his evil outlined in the text more so than any other character.
