The events that transpired in WW2 were (in my opinion) the ultimate results of the path of FEAR.
Over the past few years I have identified FEAR as being at the root of most of our problems today (IMO) and I try to combat fear where ever I find it. With awareness, love and compassion.
Fear is the result of ignorance. Ignorance is not evil or bad. Ignorance is just the lack of awareness. But left unchecked it can grow into a hideous Aberration.
"We CANNOT defeat evil with evil. We can only defeat evil with good". (Buddhist quote)
There is great power in love. Healing power. The power of example.
In my present state of awareness I could never condone that behavior (of Hitlers concentration camps). As a matter of fact, I have been opposed to violence my entire life (except in a last resort scenario, defending myself or possibly others less able to defend themselves)
But if I did find myself in a situation like that (WW2) I like to think I would seek to help the wounded, ease the suffering, and try to make a small difference (hopefully I would possess the courage to act according to my conscience)
Pretty much the same code of conduct that I try to follow today.
In terrible situations like WW2 there were many people rising to greatness by performing tremendous acts of love.
Wherever there is a "wrong" being committed, there is a tendency for people to react with anger, outrage and condemnation. But as Jung said: "Condemnation does not liberate, it oppresses"
And I have come to recognize fear as being an extremely painful condition, like a disease, so my response to "wrongness" has evolved into a more sympathetic and compassionate response. So if the sickness is being caused by ignorance or fear, it can be helped with awareness and LOVE.
I believe that (as Eckart Tolle says) "It is not the situation that is painful. It is our thoughts about the situation that cause us pain"
If this were true then we would never have to have laws or teach our children anything. Just let the level of awareness and states of consciousness of the situation be the teacher.
That is not the only conclusion that one can derive from my statement. We should teach children and increase their awareness.
We should try to reduce ignorance by spreading awareness, and teach our children not to live in fear, but love.
But then, actions always speak louder than words.
It is just my opinion but LOVE really is the answer
