The problem is to reach this quest, I knew there was this quest when I tried the evil path but didn't succeed reach it without to to have fill up high enough the soul meter and get some weird variation as if I was a nice good guy, quite unpleasant.

In all case it's a delicate path choice and good for replay when you already know the game, I doubt it's a good advice to suggest start with this path.

I see the evil path sort of funny with its excessive extreme approach, the evil NPC is a funny one.
