Actually, I think Bartle would find playing Destruction works out just fine. The point of his argument is not that the objects to torture and morally questionable actions in MMOs (which is how he originally came off sounding) but that he objects to Blizzard's careless handing out of such a quest to groups that should ostensibly object to it, yet the quest makes no attempt to reconcile your character's willingness to torture someone with the moral underpinnings your faction should have taught you. He's objecting to Blizzard butchering the story and lore, in other words.

In WAR, if you roll Destruction, you are choosing to join one of several marauding groups that have a long history of rape, torture, thievery, and murder. Such a quest would not feel out of place there, so he wouldn't have a problem.
