There are bunches of people within religion who are good people and the religion helps them to focus on humanitarian things. So I don't lump it all into making bad people worse. It sometimes gathers good people together to do greater things as a group. But within their groups, it's a shame that they cannot see that they could do the greater good without the religion and their assets would go further toward the humanitarian acts were they not drained by the pomp and circumstance.
And yes, there is always a danger, even within such groups, for the religion and/or it's leaders to make good people do bad things in the name of their religion. If they joined the Red Cross or Green Peace or some other groups, they could still do greater things as a group.
