I think we don't really know how people felt back then, do you know of any records of how people felt? But I know humans are humans, and they feel, have emotions.
What circumstances do you feel abuse is good since you don't believe it should be labeled bad.

I feel things are what they, no matter how one labels it. I think we are pretty certain some abuses are bad, no matter how one labels it. I am sure my mom would say, well I just go up set, or I was trying to stop her from wetting the bed. But burning me with lightbulbs are bad no matter what the intention was. In fact I was told my bed wetting at an older age probably had to do with child abuse to begin with.
