The evil route is just punitive and boring tbh. I tried once and got almost finished Act 2. In Act 2 already missing so much and then I was wondering what could've been left for Act 3 and I just gave up.
So, for now, for evil, you get one rushed unfinished companion. No rewards, nothing that justifies your actions except the good old. Oh, I'm evil, muhahaha, twirl my villain moustache.
