I once heard a story. The protagonist of the story was a dog that kept biting itself until it was bloody and bloody and refused to stop, because it felt that if it tortured itself hard enough, others would not hurt it again. The ending of the story is of course a happy one. The hurt it suffered was finally healed by infinite love, and it lived happily with its new owner. Unfortunately, humans are much more complex than dogs.
