I always come out sounding like a psychopath with this but... killing that annoying fucker in WRPGs that let you kill anyone.
Cockblocking me from saving the world? I'll fucking kill you and take the quest item off your dead body.
Cocky bastard sicko leading some group of sickos who think they have the power to negotiate? You're all fucking dead.
You want to hang around me but all you ever do is whine about unimportant shit and hold us all back while starting diplomatic complications wherever we go? You're fucking dead.
Insult my dead dad, who was a goddamn saint, to my face, while telling me I'm self-entitled brat who didn't accomplish anything real after I fought like 2000 mutants just to arrive? I'll let my dog kill you.
Corrupt asshole who is oppressing people and always protects himself with guards? I'll sneak into your house and kill you in your sleep.
I think it's mostly satisfying because of the hundreds of times in gaming you have your character mope around helplessly because someone won't open a door for them to go save the world or some stupid shit like that.
