I dunno about that. For one, Apollo has always been the idealist. That's exactly what he's doing here, and it especially fits in with the added knowledge that he had wanted to follow in his grandfather's footsteps. On top of that, he just suffered a huge loss which can make someone do all sorts of crazy things.
I'm enjoying the trial personally. Of course, I can see why a Baltar hater might not enjoy it so much
As an aside, I just recently discovered this podcast and think it's pretty good. If you're into podcasts and/or listening to people talk about BSG, you might want to check it out
