I'm not even a role-player, but this is one quest I refuse to run.
It just feels wrong.
Im Neutral, so I don't really care about slaughtering Innocents so long as I deem it a worthy task. And thats the thing I like about neutral characters; they can do anything they want to do as long as they deem it fit. Alignment doesnt matter. Heck, if I wanted to stomp over to Turbine's office and slaughter everyone inside ill do it as long as I reasonable rewards and law immunity. And if I also wanted to do community service for Turbine I will also do that if deemed necessity. Thats not to say those things will ever happen though...
Plus I need the favor and the XP. Loot stinks in that quest like a roadkill skunk. But regardless, if you don't want to do the quest, then DON'T. For its level it gives stinky XP anyways, plus the favor isin't that high either, so its not like your missing out on EPIC content...
