Genesis 6:6

And it repented the LORD that he had made man on the earth, and it grieved him at his heart.

1. The LORD was filled with sorrow and grief over mankind that had become so wicked. (I'm stopping short of saying the LORD wished He hadn't made man on the earth - that would suggest He made a mistake in creating us or that He was surprised at how wicked mankind had become, which I don't believe. If He had really believed He made a mistake, He could simply have caused the flood and neglected to warn Noah about it.)
2. It appears God is a male.
3. The LORD experiences deep emotion. He is an emotional being.
4. The LORD cares very much about the people on the earth.
5. Wickedness is damaging to people - so much so that the LORD grieves over us when we engage in it.
6. It is God-like to care very much about others, and to grieve when bad things happen to them - whether brought on by their own actions or not.
