Complete non-violence is complete absence of ill-will against all that lives. It therefore embraces even sub-human life, not excluding noxious insects and beasts. They have not been created to feed our destructive propensities. If we only knew the mind of the Creator, we should find their proper place in His creation.
Freedom is not worth having if it does not connote freedom to err. It passes my comprehension how human beings, be they ever so experienced and able, can delight in depriving other human beings of that precious right.
