I think Michael. Only God is omnipotent but the two beings who are closest to Him in power are Michael and Death. Death couldn't undo the damage Michael did to Sam and it would seem that Death was wrong about souls being unable to be destroyed - Demons are killed frequently and in 7x19 some ghosts were destroyed.
