You've got a friend

A short off-the-cuff blog today because my mind is otherwise engaged. The world of a friend has reached crisis-point where the choice is between keeping the peace or doing what his conscience demands. With option A) his world stays intact but he is unhappy in his soul. With option B) his world falls apart but he is morally in the right. How can one advise? My sympathies are entirely with him, and if ever he needs someone to talk to I hope he realises I am here.
