I would assume, that 'to love God with all one's being' would actually entail good deeds toward man. I would hope most atheists acted in the same way.
Could you and I be doing the same things, but motivated by different passions? Would your God not be equally honored by my deeds, or would they not be worthy since not motivated by a desire to love God?
If I love God, I will keep His commandments -- of which thse second-most-important commandment is to love my neighbor as myself. I work at #2 because I embrace #1.
I think I already answered your other question, or tried to. It's good that the child-molestor drives the speed limit. He's still a child-molestor, though, isn't he?
