"I find the jibe claiming I am naive an inappropriate counter-argument. "
Sorry, that's not what I meant to do at all. I apologise - I really didn't mean to offend you.
"To define sanity as being unaware of what you are doing, sounds a limited definition to me."
It is. But unless I'm mistaken, that's legally what you need to prove to qualify for an insanity defence. It just proves it can be something of a grey area.
"I think those Nazis with the power to command the actions were insane, yes."
Why? Because they were guilty of terrible crimes? I think the idea that by default means they were insane is unrealistic and obfuscates the real lesson that they teach us. The fact that truth might be uncomfortable doesn't mean we should dismiss it.
"To be unable to understand right from wrong must indicate the the mental processes are not working properly, which must at least indicate possible insanity."
These people have an extremely strong sense of right and wrong - they believe that what they're doing is necessary, just and for a good cause. And there's ample evidence to suggest that 'ordinary', 'sane' people can be convinced to do extraordinary, 'insane' things quite easily. They can also, I think be convinced to do extraordinarily good things, too. Drawing a line under it and just saying 'oh it's insanity' just seems a bit incomplete to me.
