No, I wouldn't go that far. I know the Old Testament pretty well, and the whole "anger and jealousy" thing is, I think, overplayed. First, the OT has quite a number of passages about his love for the earth and man (e.g, the Creation sequence, the Exodus, many of the Psalms, and the prophets.) Second, let's not forget his justice. He gave his rules, man screwed up, so God, if he exists, has every right to be mad. Why? Because his people, who he loves, are being hurt and killed. He values man, and does not much like men abusing others. Most of Exodus, Leviticus, and Deuteronomy deal with social relations, what to do if men mistreat each other.
Also, look at it from God's perspective. He is the one God. Man makes dumb stupid idols. If I'm God, I have every reason to be angry.
Finally, let's look at the New Testament. Christ, the Lord himself, died on the cross as an act of MERCY toward mankind. Not hate. And we can all agree that Christ, whatever you think of him, was a good man and great moral teacher.
Hope that cleared it up some. Got any more questions?
