"That is not dead which can eternal lie, and with strange eons, even death may die". H. P. Lovecraft, quoted from his own fictional tome, the Necronomicon. In the comic book work of Neil Gaimain, death was represented as a goth young woman wearing an ankh. Death is gender neutral.

Only if every last living creature in the universe is dead. It'd be a pity if he wanted to commit suicide but couldn't for a 100 million years or so.
You cannot kill that which does not live:)
Death is an outcome not a participant.
