Kudos for the nonviolence. :)
I just watched a surgeon slice open a woman and save her life and the baby. Blood was everywhere, it was pretty violent. Nothing wrong with it.
Violence != Malice
Mergiraf looks pretty awesome though.
Surgery is not a harmless procedure. But the surgeon must decide that the patient is more likely to benefit overall from it.
But we humans that use these animals as metaphors when trying to improve our communication skills can apply a moral judgement and say that this way of communicating is better than that way. But we literal minded often get derailed when the metaphors are not 100% solid so I often think that metaphors are bad, or at least risky. (but I like these specific metaphors in nvc somehow)
