Azrael

"Azrael" isn't usually considered to be have a bad association with death. Azrael is simply supposed to be the one who takes souls wherever they are meant to be after they die. Not the "Grim Reaper" or anything like that.

I personally think it's a great name, with a unique sound to it that would be interesting to others while not standing out so much that it would draw negative attention.

Very beautiful name. I don't think the meaning is that negative; Azrael is not the one that brings or causes death, he's the one that helps the continuation of the process by freeing the soul from the flesh/the corpse. He just fulfills his job, and that's not such a bad job after all. :D
