Why animals are aggressive towards each other is usually for dominance and like that is their territory not your territory.
Sometimes fish are aggressive because they may be bigger than one another and think that they are stronger. Sometimes of they are chasing one and tearing at its fins it may be telling that one its time to spawn!!
Cougars are actually very reclusive animals and not normally aggressive. They usually go out of their way to avoid human contact and rarely attack. However, they can react quickly and aggressively when going after a prey animal.
christians must protect their animals as it is part of Gods creation
It depends,... if they get abused and are scared if the abuser then they might be less aggressive But if they dislike the owner or person who abuses them then more likely they'll think badly about all people and be more aggressive

She will let the other animals know when to leave her alone. When you see her being a bit more aggressive towards the other pets in the house, separate her to a comfortable spot. It can stress out the mother if other pets are too curious, but it will not cause birth defects at this point. If you have questions, call your vet.
Pitbulls, no matter the bloodline, are mostly non agresive towards humans.
It could be a number of things: the dog is being territorial, isn't socialized enough (thus being unsure or afraid of strangers, or has learned to be aggressive towards other people), or it is dominant over you and thinks it's protecting you against other people. Another thing is that you probably inadvertently tried to reassure the dog by petting him, only this caused him to think it was okay to be in this state of mind (afraid, unsure, aggressive, dominant, territorial) towards strangers.
i think it is to eat other animals
some animals do enjoy it like rattle snakes and other animals like that!
