So Chapter 6 starts with The Jesus realizing he made the faults of man to be limitless, but there is a shining star...

Genesis 6:7-12:
7 And the LORD said, I will destroy man whom I have created from the face of the earth; both man, and beast, and the creeping thing, and the fowls of the air; for it repenteth me that I have made them.
8 But Noah found grace in the eyes of the LORD.
9 These are the generations of Noah: Noah was a just man and perfect in his generations, and Noah walked with God.
10 And Noah begat three sons, Shem, Ham, and Japheth.
11 The earth also was corrupt before God, and the earth was filled with violence.
12 And God looked upon the earth, and, behold, it was corrupt; for all flesh had corrupted his way upon the earth.

And so The Jesus, who had obviously also eaten of the Tree bearing the fruit of the Knowledge of Good and Evil, knew the only way to stop corruption and violence was to get a little violent himself.
