"Logically"
You keep using that word. I do not think it means what you think it means.
As an Atheist, I've lived through the situation where a relative had lost a child. I found it best to leave her alone with her grief; her husband consoled her, as is his spousal duty (and as he was the best person in that situation).
On the other hand, at the funeral we used the opportumity as a celebration of his brief but fulfilling life, playing his favourite music, regaling each other with positive experiences about him in our memories, and so on.
Just as the late great Arthur C. Clarke wanted after his death, he didn't want people to grieve for him, but to celebrate his good works: his literary achievements (he's acknowledged as the Shakespeare of Sci-Fi); also how he is remembered every second of every day, with his invention: the telecommunications satellite. What better way to celebrate his life?
Just think on that, next time you watch something on cable/satellite TV, use the internet or make a long-distance phone call, P-Marlowe.
"with an attitude like that, the Atheist should be walking through hospital wards with a AK-47."
Bad analogy, much? Besides, we Atheists live our lives by the simple philosophy of 'Treat others as you would want them to treat you'. Also 'I wouldn't like to be killed/harmed, nor have my property stolen/damaged, so why should I do the same to others?'. Not to mention 'Commit acts of gratuitous kindness' and 'Be good for goodness' sake'. See? All the morals you'll ever need. Unlike the 'superior morals' of you fundies, eh?
So why didn't the threat of eternal Hellfire stop Timothy McVeigh murdering 168 people - including 19 children - in the Oklahoma City atrocity? And he was a right-wing Fundamentalist Christian.
An AK-47 wasn't sufficient for him. Amirite?
