Well, Jesus did say a lot of terrific things, but the guy had a real attitude problem. If you read the gospels carefully, you'll see he got irritated and pissed off rather a lot. He hated having his authority questioned, and rarely missed a chance to snap at someone, even though he usually granted their requests when he'd calmed down. And for gods' sakes, the guy killed a perfectly innocent tree because it didn't have any fruit for him to eat when he felt peckish. That's an awfully prickly dude right there.

But for the most part, he did teach good stuff.
