Who killed the most people in the Bible?

Who killed more people in the Bible? God or Satan?

God: the high figure is 33,041,220 people. This is a high estimate. Others estimate a much lower figure of 2.8 million. 
Satan: 10 people (seven sons and three daughters of Job) but these murders were allowed by God as a part of a wager so technically, God is also an accomplice in these deaths.

There you go... Just more proof that if God does exists, he's a fucking asshole.
PS. God only beats Ghengis Kahn by about 3 million...
