[@Stabby] [b]Exactly[/b]. How can you call that evil? That's just surviving. They need souls to survive and doing something that basic, even if it is at the expense of other..lesser creatures they sure as hell can't be considered evil for that. But as we know it, evil is relative to everyone but here's the thing, everyone who summons It, they consider them a blessing and those who didn't summon it, well almost no one knows so they can't really have a dilemma on whether that creature is evil or not. 
So, almost everyone who knows of It's existence considers It a useful "tool" on getting work done, a "good" thing for them. By this standard they are actually good... I'd like to rephrase my declaration of his alignment, he is actually [b]good [/b]although he kills people.
