My answer is "No!" I believe to read such a meaning into it is to miss the point. In fact, I believe it to be a powerful story of the love of God towards humanity.
In Genesis 4 we have the first murder. Although the murder itself did not please Him, God still valued the life of Cain so much that he did not want anyone to kill him: God vowed to punish anyone who kills Cain. But, at this stage God did not outlaw murder. That came later.
Fast forward to the flood. God was sad that His creation had turned so evil, so He decides to start afresh, cleansing the world, but keeping alive the only people faithful to Him: Noah and family. I believe that such mass destruction brought so much pain to God because it is at this stage where He makes two promises:
- He promises punishment for those who would kill another human (God does not wish anything which is made in His image to be destroyed). (Genesis 9:5-6)
- He promises to never flood the earth in such a way again. Ever. (Genesis 9:11)
God is not a God of genocide: He is a God of love. He loves His creation so much that He hurts so much when He sees it destroyed.
