In the ROTS novel, Yoda and Obi-Wan are having a discussion about the war. Obi-Wan says that he would sacrifice any jedi's live, including Yoda's, if that were to end the war. Yoda replies something like: as you should, and I would do the same in sacrificing you. Yet in AOTC, Yoda let Count Dooku go to save Obi-Wan and Anakin from the large piece of machinery. I expect this may be because Yoda wanted to save the Chosen One, but he usually does not go against his morals. Thoughts?
