We should be getting exp for each encounter, whether it was resolved peacefully or violently. The way it is it just punishes the player for not being a murder hobo. And not even "give less exp for peaceful", no. If the total exp for that counter by killing would have been 200, then the peaceful option should be 200 too. You had to pass a skill check(s) to get that peaceful route, you should not be punished for how you made your character and what you did. Missed loot because you didn't kill? Sure. Exp? No, players should get that either way.
