El Shaddai is another name for Yahweh and is mentioned in the bible many times to denote God as a destroyer which he is to an extent. Any religious person knows God destroyed all people during the flood, mythological or not. El Shaddai is translated "God, my destroyer." El Shaddai is the avenger of Israel, and anyone who harms Israel, "the Jewish people" at all, such as making them worship other Gods or intermarriage, etc., will experience the wrath of El Shaddai. Destruction can also come through acts of nature, enemies, animals, etc., and people in God's will can be pillaged, plundered and killed, women and children, in his name.

Don't have to be a theosophist, whoch I'm definitely not, to know this.
