To me it doesn't matter. He will likely deal with these problems the rest of his life. He won't be healed in this life. If he was an alcoholic, I wouldn't take him to pub.

Since I don't know your exact faith, I can't really answer what you mean by being healed, nor can I really discuss it.

I view it in this way, there are scriptures that say we shouldn't allow others who speak other religions into our homes and ones that say if we so much as give a man of God a glass of water we will be blessed. It becomes my choice on if I want safety or blessings. You aren't wrong to deny them entrance, I just choose to bless others.
