Again, Christian Ethics - which is not the same as regular ethics - for the very reason you question it - is a class you can take probably as an online course from Lee - where you will freely discuss these things. How you treat your neighbor is how you treat God (how you do it unto the least of these - is how you do it unto me). Hitler is a murderous villain - I owe him nothing - and I don't believe God believes I owe him anything. There are others that feel differently. Military men that shoot invaders - don't consider it murder - because they are defending other folks from being murdered.I was recently at the Holocaust museum in DC where there is an honor roll of folks that saved Jews. One lady, a young housekeeper, saved 18 Jews by hiding them in the attic or cellar of the Gestapo major she worked for. (The rest of that neighborhood had all Jews liquidated.) Unfortunately, he found out but agreed to keep the secret if she serviced him regularly. She did. 18 Jews lived due to that action. Was fornication ok to stop 18 murders...19 if you include she was a goner, as well for hiding them. (the lesser of two sins) Irene Gut Opdyke (the housekeeper) (b. 1921) felt it was. The Jews agreed with her. I agree with her.Are you too holy to agree with her?Is there a third way - where you don't help killers but don't lie either? Perhaps - but I am convinced not always. When you face that situation - you will be glad you took the class where you can resolve these issues in your mind before being confronted with them and perhaps feeling guilt later
