Mine will tong feed or eat from a bowel out of my hand. She does seek out attention and interact, even when on the floor she will come seek me out. As for an "aggressive" monitor (such a bad word), it depends on the enclosure. If it's a proper large enclosure, it will avoid you, run, stand it's ground in the back puffed up like DONT COME NEAR ME. If it's small, and the animal feels cornered it will bite of course- it's the basic fight or flight reflex that exists in all animals.
