Sig, I would expect you to do just that. Tell them to "get lost or be killed". They made their bed.
What I struggle with is that I could not do just that.
Some think of Jesus Christ of carrying a sword to kill his enemies and justify that "sword", but I do not.
No different than how Muslims interpret the Koran IMO as far as killing others.
A very long time ago as a grunt working, I stopped to help a old lady shoveling her driveway (I could have gotten in a lot of trouble for doing so).
I stopped to help this older woman because I remembered what my mother had told me, to treat people like my mother would expect me to treat her and my father if I saw them in need.
When I saw that old lady working to shovel her driveway, I couldn't help but think if that was my own mother, so I stopped and helped her and did her driveway.
What I have learned in business is do what it right and let the chips fall where they will, and generally, it will work out.
When I give a bum panhandling on the street $20, I don't care if he buys drugs, it's what my intent is, NOT his (generally I offer to buy them food in person and see where it goes...).
When it gets to the point that I say no to everyone in need, in my own line of thinking as a Christian, I'm ready for Heaven as I know what Heaven is to myself and I'm done with being an arsehole
Perhaps when you lose a son, it gives you a different perspective and being more at ease joining him instead of fighting for your life at all costs so you can breath on this world to give yourself another day
For myself, my own God judges you on your own actions even if you can't how everything plays out 100 years from now...
