"Inflicting injury, suffering or death on an animal, absent of provocation or hostility, gives an individual tremendous psychological pleasure, the malicious youngster rehearses his sadistic attacks - perhaps on animals, perhaps on other people, perhaps on both - and continues into his adult years to perpetrate the same sorts of sadistic acts on human beings. His attacks on animals are serious and personal. He chooses 'socially valued or culturally humanized animals - for example dogs and cats - against which to carry out his sadistic aims but he is likely to repeat his abusive behaviour on a variety of animals. If he later finds a socially acceptable means of compensating for his sense of powerlessness, then he might very well escape the grip of violence perpetrated against humans. If not, his early experience with animal cruelty may become a training ground for later committing assaults, rape, and even murder."
