beyond that, and this is my opinion, we don't have souls. Our brains are what we are. Go by any popular neuroscientific case study regarding lesions, like phineas gage, and you realize that personality is malleable beyond a "society" sorta context.
I mean, i'm not sure, so see ya in 3 years or something when i'm less dumb. despite the brain being everything, we still have voluntary functions which is weird, and we can overpower our body's inhibitions and do things that are evolutionarily bad, like kill ourselves or some shit.
