@Chet31 go back and read his back story -.- Abel is like god incarnate to him; he finally has someone who can keep up with him. The assassins and the drones were all in an attempt to expose how truly capable Abel is. "You won't be able to hold back this time!" *take care of it with a single finger* "fufufu, looks like I have more research to do"
I don't really consider characters like him as antagonists, as they are not villains or villainous. By rom/com standards, Is the girl who is trying to get you and your childhood friend together a villain? What about the fujoshi who spies on you because she thinks you have a BL relationship with a femboy?
