Frank, you wrote
some of them profess religion and do good works (in my view in spite of their religion).

I suggest that your view could be changed by asking them why they give up so much of thomselves to help others.
They will very soon put you straight.

I have mentioned the Salvation Army who do so much, especially in offering shelter and support to those who have fallen through all society's nets. How can you say that their faith is irrelevant to their actions?
Talk to some of them!
