I for one would prefer the evil MC get something along four endings. Jail, murdered, go completely crazy, and get away with all of it. Each for different reasons. The catharsis of him getting karmic retribution would be nice, and if i'm being completely honest, the fantasy that justice visits folks who deserve it is nice. At the same time, some of the scenes on the evil route seem to show that dude is getting disturbed. And finally, well, not everything is fair, and as I said before, the kinder path is more meaningful by the fact that the crueler path is more rewarding. It makes the choice one that matters, and not one that is done just to avoid punishment.
