Well, he's doing it as a martyr of sorts so that the non-magic users can learn how to better fight a magic user. The goal may or may not justify the means depending on one's viewpoint. That being said, having the prince out of all people fill that role would be... unlikely. If they would do any such thing, i'd think they would leave it to less important people. Letting the potential future king learn magic would be a huge risk that would probably alienate him from his subjects.
