  Human beings kill each other for reasons such as revenge, self-defence, in suicide, others for entertainment – not to mean that killing is justified. However, humans are not the only species that kill each other. Wolves, for example, kill each other constantly in territorial disputes. Lethal violence in humans has been shown to be 7 times more than other animals, which is extremely high.
