Can you provide an example of what you are discussing?
We generally consider killing innocent children to be evil (lets ignore the abortion thing). We also bombed German cities knowing that innocent children would be killed and hailed those that dropped the bombs as heroes.
Yes, cuz good people would just let Nazis do whatever they wanted to without any resistance.
That's nonsense. The problem is a problem of the logic of time. The real problem is that good people are often convinced to be a N. is a good new thing. So some are walking this wrong way - manipulated from a continuous brainwashing stream of more and more weird propaganda. And when you are in the middle of the swamp, then it is difficult to find a good stand.
Actually it's pretty easy for those who have morals
How do you know what's easy for people, who have moral?
and aren't putting so much effort into lawyering their way out of false dilemmas.
A complex empty phrase
Good people?
aren't required to stand and do nothing to stop evil;
Do they? How do you know? Where from comes this idea? Mr. Satanas?
just because evil people will hide behind good people
"Evil" and "holy" is the pair of words. The other pair of words is "bad" and "good". Who is holy is not always only good. And I never saw that for example evil Islamists (=bad, godless people, who misrespect the belief in god and misrespect the life of other human beings in most evil ways too) - hide themselves behind good people. They just simple murder, who shares not their opinions. It's easy to murder enemies and to declare everyone else to be an enemy.
and get them harmed and killed doesn't make those people who aren't standing by but actively eradicating evil guilty of some 'lesser evil'; the blame lies entirely on the evil people and their actions that created the situations. 'Swamps' present no moral ambiguity or confusion to those with genuine principles.
Your little confusion in the beginning of your speech grew now to a bigger confusion. Try this way:
"Lass die Liebe in deinem Herzen wurzeln,
und es kann nur Gutes daraus hervorgehen."
Augustinus
