I think you can't be good or bad in this world. You can play in the little grey area. We are human beings after all with lots of flaws. God is created by us, hence it can never be omniscient. Most of the times things happen because of the choices we make. We call it a miracle when we never think of a reason behind the event. Thanks @thethinker007 for pointing out a great question at the end of your post. :-) It's all about perception and I think the man did the right thing by saving his own ass. Kill the bad potatoes :D
