Hmm...
Well, I can't say much about plays, considering I'm thirteen and I've only seen two in my whole theatre- going years. I've seen THE WOMAN IN BLACK in London and THE PILLOWMAN over here, (Yes, you read that right.) but I'm seeing DOUBT Saturday night, so I'll see how that turns out. I enjoy plays.
As for your question, I think Michal says he acted out, "The Little Jesus" because he had no choice. He was going to be executed soon anyway, so he might've figured out that it wouldn't matter if he said he did the crimes anyway. He did half of the crimes anyway, so since he's mentally retarted beyond repair, he thinks that telling the truth will bring him to the light when it really wouldn't. Who knows. It was a very interesting play, and I liked it, though it dragged in parts.
