I actually like him. It's especially cool when he destroys mana. He crushes it, then wipes his hands (a clean demon). But his improved version is ugly. Fire comes out of a hole in his head, and he holds this vial in his hands, into which he puts the mana. And that's called stealing! That's called accumulation! It would be called stealing if he used it himself (and rained meteors down on other people's heads). But he just puts it there and smiles slyly.
