The answer to "Who killed Azrael" depends on which Azrael you mean, as it's a popular name for characters in comics and shows: Jean-Paul Valley (DC Comics) was killed by Biis and Scratch after being shot, while the Supernatural angel Azrael died from injuries in a fall from Heaven alongside other angels, but the name also refers to a figure in Islamic tradition not typically "killed" but rather an agent of God.
Azrael was eventually presumably killed in a fight with his two greatest enemies, Biis and Scratch. He was shot through his armor by multiple teflon-coated bullets, and then tumbled off of a balcony with LeHah.
Azrael is often depicted in lore as the angel of death and/or retribution. Ironically, Azrael himself died during the fall of the angels, which was the result of Metatron's retribution against his brethren. Sometimes Michael is represented as the Archangel of life and death.
Lucifer and Azrael are angelic siblings and the children of God and Goddess. They were very close and enjoyed spending time together during their time in Heaven.

After the First Seal is broken, the angel Uriel began working on converting other angels to his cause of releasing Lucifer.

Azrael, often referred to as the "angel of death," is a significant spiritual figure in Judaism and Islam, as well as in some new age belief systems. In Hebrew, his name means "whom God helps," and he plays a crucial role in facilitating the transition of souls from life to death.
The name appears to be used for both male and female children in the US, though it is traditionally considered masculine. The mystical and powerful connotations of Azrael likely appeal to parents seeking a name with deep spiritual significance or dramatic flair.
Since the 14th century, European art connected each of these various physical features to death, though the name "Grim Reaper" and the artistic popularity of all the features combined emerged as late as the 19th century.

az'-ri-el (`azri'el, "God's help"): (1) One of the leading men of the half-tribe of Manasseh, East of the Jordan, who with others of his tribe was carried captive by the king of Assyria (1 Chronicles 5:24ff). (2) The father of Jerimoth of the tribe of Naphtali in the reign of King David (1 Chronicles 27:19).
