That's armchair philosophy which is fine to do as recreation but is a fool's errand to attempt in real life. Firstly, you don't know the future so you don't know that your supposition will turn out the way you envision. To reference another work of fiction, Dumbledore told Harry that prophesies don't set the future in stone so he shouldn't get too worked up about it. Did you consider alternatives? Did you consider that you could be wrong? You should never underestimate your limitations when it comes to predicting the future.
Secondly, the emperor has two sets of priorities. The first is the health of his empire. The second is his family. He is responsible for the well being of his daughter and, fortunately, he takes that very seriously. So, to ask him to put his young child into harm's way when he already has other considerable powers to use is to ask him to disregard that responsibility. For what reason? The priest is ignorning the emperor's capability to balance his own priorities and values and is pushing his own outsider's values onto him. The emperor is capable of problem solving all on his own. So, when he replied "Are you looking down on me?" he was correctly admonishing the priest for looking at the problem with tunnel vision.
