Creeping Death

Creeping Death was a biblical angel sent by God in the story of Moses to kill the firstborn son of Ramses as punishment for not letting the Israelites free from Egypt. It was the final plague that convinced Ramses to do it. Metallica made a song about him in 1984 from their Ride the Lightning album. His real name is presumably Azrael. Creeping Death can be seen as somewhat of a vigilante or even bounty hunter-like angel by some people's standards even though what he did was for the greater good and by God’s commands.
