Sometimes he watches alternate selves and their petty little obsessions with mortal, matter-based creatures. How disgusting. He can't imagine descending to that level, can't imagine actually spending time with the things, wearing their forms, talking to them as if they were people. The obsession with emotional connections to a particular one specifically appalls him.
Not that he runs the risk of that problem. When he was assigned to deal with his universe's version of the creature so many of his other selves are obsessed with, he just killed the thing for defying him, and moved on.
This reassures him. If so many of his alternate selves have been so corrupted, it could have happened to him too. Now it never will.
