Millions and millions of people killed animals and each other for hundreds of thousands of years, as the normal course of life. In order to survive, in revenge, and doubtlessly sometimes just for the hell of it.
Were every last one of them mentally broken?
I think there’s a chauvanism to modern thinking. Once during our country’s history, many people could justify to themselves, and sleep well at night their ownership of slaves. Were they, every last one of them mentally ill? Perhaps, but perhaps what we call mental illness, was normal and accepted in times past, and perhaps some of what we consider mentally illnesses today, will be seen as absolutely a normal part of the healthy population in the future…
I’ve been smoking some funny stuff though, so I’m thinking a lot less judgmentally. Perhaps I’m not making sense.
