victim: All people except 8
Massive flood just happened which covered all known land to the highest peaks and it has killed all living people except 8. God claimed he caused this disaster as he was angry on people living on Earth. He claimed he did let know people in advance, via man named Noe, with whom he spoke in person. Noah then tried to convince other people and he had build a massive ship for the protection.
God did not receive any punishent for this massive genocide, although he promissed he will never do it again (at least not by a water).
