I'm a sadistic fuck that's been made to have the caring range of a rock due to childhood abuse

I'm fine being that way, it's just not conductive to maintaining relationships. Been there, done the whole 'be yourself bollocks' - the results were shit. Pretending to care far more than I do, and constantly suppressing the sardonic and vindictive tendencies has been far more pleasant

'just tweak core aspects of your personality' is exactly the opposite of being yourself
