So.most of us just make innocents and quest givers invulnerable to death or we have attacking them trigger the guards to run out of nowhere. In a single player game, I guess it is something to do.don't ems weird. In all my years of playing online games, I have to say that I never did get why killing the shopkeeper was fun, other than ruining game play for others. But not sure what is fun if they just stand there and let you kill them. Killing combative NPCs is fun I guess because they fight back. PvP is fun because you have to actually work to kill the other player. But I would imagine, that for most people, it is not that much fun. Maybe in a multiplayer game keeping others from getting quests from dead noncombat NPCs is enough for you to have fun.

I am imagining that if you like to kill stuff in games, you want that action of yours to actually DO something in game. The OP asked if it were fun, important, or necessary, not whether it was moral. They are just a bunch of polygons after all. You know, it is not a bad thing to kill NPCs in games.
