I would say death can most likely kill anyone or anything from any world or dimension, except the Darkness. And saying he can only kill what's alive doesn't really hold up, as golems, ghouls, zombies, and nachzehrer, for example, are considered to not be alive, yet of course death could easily kill them. I would say death's inability to kill the Darkness has nothing to do with her being living or not, but due to her immense power, that to at least some degree, is higher than even God's.
