You could try finding a better way to comfort children. Maybe not saying the dead person will go to heaven, but something like 'He is now sleeping and comfortable', or he is in a better place (that better place being oblivion, for some a lot better than heaven or hell). Something like that. Just tell the kid that you live and you die, it's like going into sleep and if feels really comfy full of peace and tranquility.
Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
