he wasn't that great. Fanboys are always talking like he was the best thing since sliced bread but really he was just the only ascian so far with a personality and a coherent motivation. He really only looks interesting because the other ascians have all been mustache-twirling cardboard cutout villians.

Bottom line he wanted to kill lots of innocent people because he couldn't move on from the life he lived over 10,000 years ago. It was all one big pathetic pity party for him that he insisted on dragging many many uninvolved people into. Good riddance.
