the way walter was killed, he deserved it, I thought. I also thought it fitting that the Crimson King's eyes were left on the balcony. He was not meant to reach the top. Who knows what Roland will find when some day he finally reaches the top and is not sent back to the desert. In my opinion, he is never meant to go to the top either. His destiny was to save the beam, which he did. If he just had stopped there, all would be well and he could reach the clearing at the end of the path, maybe even with his new friends. The Crimson King would still be stuck up there on the balcony never causing anyone any more harm and the world could move on.
