“It’s probably Matt Mercer’s fault.”
A game where my PC can do even the most horrific thing - murder in cold blood - as if it were no different from preparing a meal or mending some armour seems to be one in which I am just controlling the character like a piece moved around a board. That character has no inner life. No doubts or hesitations.
In my mind that's where roleplaying comes in. (And also the word "murderhobo".) I, for one, do feel hesitation (and remorse) with most of my characters for committing murder. I don't need dice to tell me to feel that way. But if my blood is up over something outrageous the NPCs have done, I feel less hesitation...although later I might feel just as much remorse. Depends on the circumstances.
And if I did use the dice to determine how my character felt, I don't think I would personally actually feel it anymore. Or perhaps the dice would tell me that I have no qualms about killing them, but I personally would still feel unsettled about it. Now I'm even more disassociated.
I'd much rather actually feel all this than just perform it. Even if that means I'm really roleplaying a character who is, to some extent, myself.
