That's not really weird only from an angel. As an Asian I can tell you that look isn't very natural (definitely isn't what common among those are usually considered beautiful among Japanese). It's a similar aesthetic that many people who undergo Korean style plastic surgeries would end up choosing. But also at the same time he cheekbones are too obvious for Asian standards so it kind of looks original at the same time. I just feel like the nose and face can be widen and rounder to look a bit more natural.
I think you probably miss the point here. It's really not having no self control, but just overall being a very efficient predator. When the condition allows, he makes moves and doesn't fuck things up. It's not like he just do whatever the hell he wants without thinking of the right approach to each victim.
