Seems to me that some of the people on this thread have either judged you or your friend on what you have written but I find little to form an opinion of substance either way. I do however agree that as this person is your friend, you should offer a caring front and subtly get the message across that you are there if needed. Be a friend to your friend whatever, and try not to be judgemental. If you find out some facts about the organisation which cause you great concern, confront your friend (in as sensitive a way as possible) tell him about your findings and leave it with him....still being there for him...whatever.
I wish to make clear here that this is an opinion based on little knowledge and is "perhaps" what I would do in your situation.
Be Blessed.
