One can never be sure of the end, only of the means, and so we must be sure that the means are good.
The only good thing we can do, the only goodness we can be sure of, is our own goodness as individuals and the good that we can individually do. As groups we often do evil that good may come and very often the good does not come and all that is left is the evil we have pointlessly done.
Why, the only reason for religion is that it can make you, keep you safe. If religion weren't true, then there would be no salvation, no comfort for being alive and alone, there would be nothing but living and dying - no, that cannot be so ... of course religion is true and will save me.
