Did Satan kill noone in the Bible?

The Christian devil (satan) is a Christian idea that was retconned into Hebrew Scripture. Originally satan was an order of angel, like cherub or seraphim. The satan's job was to be in opposition to man, conflict as part of the grand design. He would also be called upon to be a prosecuting attorney or even executioner. The oldest available texts indicate YHWH used a satan to rain down fire and sulfur on Sodom and other cities, and also to inflict the plagues on Egypt. In this context, satans killed a lot of people, but all under orders from the big guy himself. It truly is as Isaiah 45:7 (KJV) says, "I form the light, and create darkness: I make peace, and create evil: I the LORD [YHWH] do all these things."

Satan killed a total of ten people. All with God’s approval.
