I heard a story where monkeys mutilated and deformed a zookeeper, because supposedly they were jealous that she gave more attention to a different monkey.

Earlier today I saw a video where cops saved a woman from being eaten by vicious dogs, but she was already mutilated when they got to her.

I think such animals should be experimented on and then after the scientists improve our species knowledge on their behalf, to offset the harm they did, they should be shoved into crematoriums fully awake and burned to ash.
