Ah, yes, I was conflating the burning of the idols with Cressen's death late rin the episode.

I would still argue that Stannis was a bit of a zealot at that point. He became a true believer when he looked into the flames, but he was still following Melisandre's word from the beginning. May not have been to the extent of "I'll burn my child for the Lord of Light" but he was definitely swept up in the religion, and Shireen's death was a logical conclusion for his zealotry.
