Luke,
Just a quick, short comment. In reading over your posts what comes to mind first:
Proverbs 28:21 To have respect of persons is not good: for for a piece of bread that man will transgress.
You need to stop tying your own faith and walk up with another man. Whether or not you are disappointed with him and whether or not you should or shouldn't be concerned about what he does, the fact is that your own walk is not about him, it's about the Lord Jesus Christ.
