I know TRP preaches all that "game as amoral" stuff, but when my moral compass doesn't only make my game bad, it loses me friend groups all the time, I have to have some bare minimum for morality

I recently got thrown out of a friend group I've known for 9 years because I was happy that one of my competitors for this girl I know has cancer and is going to die.

How do I gain enough of a moral compass to not be considered a sociopath?
