And how is it that Gauis Baltar got a happy ending, I don't remember him repenting for his sins.

That's exactly the kind of stuff I actually love about the show. It's real. It's life. The most despicable character gets a happy ending. He manages to survive in spite of everything he's done, including being responsible for the end of the human race! And, to top it off, who defends him but our reluctant hero, Lee! As much as it's not what I want to see in a "T.V. show," it's what makes BSG so special for me: the realism.
