I would have been disappointed if he didnt steal his powers. It was obviously his only goal. Why would he kill that person? That doesnt help him. Glad they confirmed it quick enough though this chap.

Conflicts are said to be the characteristic of humans and necessary but that shouldn't be the case as a grace period follows it which just makes another conflict which is not productive at all.
I don't understand the hate at edge, if it's used like this then it's perfect, he has a reason to be edgy, and he's not afraid of acting on it.
Now, people like Kirito, or Light, then I can understand calling them out.
