My brother is stupid for passing out sandwiches to homeless people

My idiot brother has gotten all involved in church thanks to his idiot wife and has started passing out sandwiches with another guy from his church out in the hood. You drive a damn nice car, dress nicely and at any second those stupid junkies and thieves could kill you and take your stuff to sell it for crack. Our mother as well as myself have both yelled at him over this but he doesn't listen. Don't you think for one second those people are your friends they'd punch you in the face and steal your car to sell in a heartbeat you idiot.
