They aren't human and don't look to humans as their comrades. Even in the wild, they often fight for dominance. They probably look to humans as a source of food and sometimes maybe as surrogate parents but after a while they typically resort back to their natural wild instincts.

Its there nature they are predators that is why they are called wild they can't be trained to be nice. As babies they don't have the strength to go against their owners but when they grow up they do. Hope that helps.

I think often it is that the humans become overconfident and start to treat these large and dangerous creatures like pets, rather than showing them the respect and consideration they require as wild animals.

I've heard of stories here and there about big ferocious animals like lions, tigers, cougars, hippos, rhinos, elephants, bears, and etc. being under the care of a human provider. When they're pups, their owners give them love, support, warmth, food, and other necessities.

Is it because these individual animals are complete assholes?? Cause I know some relationships do work out. Is the "animal instinct" just a way of saying "not getting laid enough", so turning assholes and attacking their loving human companions??
