An Anti Villain or Complete Monster?

I'm designing the core villain of my story, and confused on whether I should make him an Anti-Villain or a Complete Monster. The story itself isn't too dark, at least idealogy-wise (violence, on the other hand...).

N iss an highly intelligent young man who enjoys messing with people's head and causing problems for his own amusements. He commited several acts of terrorism that practically demolished a city famous for its police competency, all without killing a single person. But he got caught and summoned to his family/clan's house, after which he got imprisoned in family prison. Few years later, his subordinates break him out of there and he decides to go to the protagonists' city, where pretty much the biggest supernatural incidents occur. After investigating about the protagonists' involvement in the start and pacification of all the incidents, he starts to manipulates each and every core member of the Agents, especially the Five-Man Band, making things spiral to madness.

To give his basic background, he's an illegimate son of the leader of a major corporation. So he is pretty much kept in secret and sent off to boarding school early in his age. He has a half, legimate, brother named Sean, who he initially resented, but after realizing that he genuinely looks up to him (after all, he is very intelligent and had pretty proud achievements, both in academics and sports), he warms up to him a bit, and grows to genuinely care about him. However, because he knows that his family would be very displeased with Sean if he's seen interacting with him, he tries to as cold and apathetic toward and stops visiting him, everytime he gets out of the school, altogether.

Also, Sean has an extremely rare ability to make people obey every single words he speaks, which went unknown until he was 10, due to his shyness and lack of words. N is the first one to figure it out (normally, if you get hit by his power's effect, you can't recognize that it had effect on you.) and thinking that his father will exploit his power, Mind Rapes him into conditional muteness.

Ok, got to go, will come back soon.

Just make N N. His personality and intentions will develop on their own.

I like that, but can you be a bit more specific on him being him? Also, are you saying that at least partially because my post was too boring to read through completely?

Locking per request.
