Regarding snapping necks, I am reminded of the English practice for public executions
that those from the nobility had the right to have their heads chopped off, while common
criminals got what was considered the more bloody death of hanging. It was considered
more merciful to have a sharp chop.

Diana is the product of a warrior culture, so her killing would not bother me. I don't have
a belief that there is any honor in warfare it is simply killing, often in our society mechanized killing.
Diana's values often speak to peace, crafting an ethical society, but she is no pacifist.
If pushed she could kill. But I have a hard time thinking of her as someone who takes a ruthless
enjoyment out of the taking of human life.
