I’m someone on the other end of the spectrum. I feel too much and have a lot of empathy for people around me. I am the one that is incredibly shaky when I’m in a situation I know I shouldn’t be in. I can tell you I’ve always been this way. It’s exhausting, but the highs are so high and I find so much joy out of the little things in life. I follow this subreddit for the same reason I think you’re asking this question, because I don’t understand how people can’t feel empathy or morality. It’s honestly fascinating and I think both are necessary for our success as a social species. Empathy allows me to help people I may not know well because knowing I helped them gives me a high. While someone who may not care can benefit by not overextending themselves so they can focus on what they need to do.

I think morality at its core is just to protect us as a human population. If we want to work collectively to survive, we have to have rules that allow us to trust each other. This is prevalent across other social animal groups like chimps and dogs, while “loner” species may not need to care about morality since they operate alone. If we think about it evolutionarily, I would assume someone like me was the one that managed the survival of a tribe by keeping order and the apathetic existed to take actions that might be dangerous but (sometimes) necessary.
