All of them.... YHWH caused the literal death through his servants, of all those who were in a spiritual death cause by Satan. So, YHWH and Satan caused their deaths. Many from the flood, were preached to by the authority of Jesus, after death, in proson, so that the spirits in prison might repent. There is still chance for some to repent after death. 1 Peter 3:18b.. he (Jesus) being put to death in the flesh, but being made alive in the spirit. 19) In this state also he (Jesus) went his way and preached to the spirits in prison, 20) who had once been disobedient when the patience of God was waiting in Noah's days, while the ark was being constructed, in which a few people, that is, eight soul, were carried safely through the water. Welcome Jesus earth's new King! Thank you Yahweh!!
