There are some fundamental questions I need answers too in regards to how a character/person functions. Currently I'm running off the id (instinct you're born with), super-ego (internalized parent), and ego (the result of the conflict between id, and super ego; or the one who makes the decisions)model; however i'm struggling to figure out which part of the mind is responsible for caring about another person. Do we care only for those who increase our chances of survival? Or for those that provide a chance for us to pass on our genetic code? Why would I feel sadness if someone I was close to died? Why would i feel anger if someone i was close to got hurt? Some would probably answer "empathy", in which case i'd ask : where does empathy come from? is it in-built? or is it learned? What part of the mind is responsible, and how does it come to be?
