LY, according to some opinions the halacha indeed does not apply in our time. Why do you have problems with the facts that poskim sometimes disagree and that there are halachic tools to deal with that in practical situations?
ZD, Schindler was perhaps a modern example of someone who acquires his world (to come) in a moment. He was indeed amoral and even was arrested twice for public drunkenness. Moreover, he joined the Nazi Party in the Sudetenland well before the munich agreement and spied for Germany. One of his survivors, Murray Pantirer said:
“He came to my house once, and I put a bottle of cognac in front of him, and he finished it in one sitting. When his eyes were flickering – he wasn’t drunk – I said this is the time to ask him the question ‘why’ ? His answer was ‘I was a Nazi, and I believed that the Germans were doing wrong … when they started killing innocent people – and it didn’t mean anything to me that they were Jewish, to me they were just human beings, menschen – I decided I am going to work against them and I am going to save as many as I can’. And I think that Oscar told the truth, because that’s the way he worked.”
After the war he was hounded by anti-Nazis as a former Party member and by Nazis as someone who saved Jews. Howvever, for what it is worth, he is buried in the Catholic cemetery on Har Zion.
