Cruelty
Cruelty is indifference to suffering and even positive pleasure in inflicting it. Cruel ways of inflicting suffering may involve
violence, but violence is not necessary for an act to be cruel. For example, not helping the one who drowns and begs for a helping hand, and watching it with disinterested amusement or pleasure instead is not an act of violence, but is an instance of cruelty.
Cruelty is inherited in human nature, and some apes are capable of cruelty too. No other animal is known that feels pleasure in seing other suffer. According to Nietzsche, almost all higher culture comes from spiritualization of cruelty.
