i mean, isn’t that kind of a universal consequence of being evil? it’s very much in the spirit of immersive roleplay to be abandoned by most of your friends when you start acting like a maniacal asshole. the only people who will stick around are those who don’t know you well enough or don’t care and are only following you because they got paid to do that
the message the game is sending is simple - if you want friends to stick around, don’t be evil. and if you want to be evil, prepare to be alone
the game is a completionist punishment all across the board though! you really can’t see everything in one playthrough
