Yes you can be evil, but that will come with a cost. If you think that by murdering everyone you will have a good time, you are wrong. First of all this kind of games are all about the story and not really the combat, yes combat is fun and all, I know. Anyway no, if you kill everyone you should just die with it.
You can murder everyone and still have a good time. You just need to make sure you know what each NPC can do for you so you know you are "done" with them when you bury a sword in their heart and watch the life drain from their eyes.
I cant wait for the full game so you can properly kill peoples souls after you kill their body.
