he went way beyond what was nessacary to achieve his goals.
and one of his goals was vengance.
vengance is evil to me. there is not point to it but to hurt someone. to cause another pain; phisical, emotional, phicalogical as an end in its self is evil. what can you gain that is good from the pain of another? nothing. there is no redieeming justifacation for pain for its own sake.
