Azrael

The Angel of Death.
Possibly the kindest and most misunderstood Angel(not a demon). Helps in the transition of the human spirit from life to death onto the spiritual plane.

A good companion to his depressed and suicidal friend, keeps them from killing themselves.
Only being who understands the want to be erased from existence. Not to spit in God's face that they don't want heaven or to depart from God. Doesn't want to got to Hell either. Doesn't want to spend an eternity with out the ones they care about, believes human life is to short a time to live.

A being who cares about your well-being.
A comforter to the loved ones of the deceased; to help and protect them in that time of grief.

Ex: Azrael , The Angel of Death my friend; how I've missed you.
