guilt as a concept is so fascinating to me. it doesn't make the situation any better. people do irrational shit out of guilt that make things worse.
I don't even particularly understand it from an evolutionary perspective. guilt doesn't suddenly stop you from doing awful things, just like how a lack of it doesn't make you do awful things.
I'm always amused by people who are made uncomfortable by my lack of guilt or empathy. are guilt and empathy the only things stopping you from being a terrible person? I think that's a lot more telling than me lacking those things and still being pretty damn decent according to most people I know.
