Re: What happened to the Klingon prisoner?
The intro to the Klingon Dictionary says that Maltz provided much of the information in it. In a way, this may have helped him regain his honor. If the Federation can speak the Klingon language directly, it makes it easier to fight against (or even with) them. Thus Maltz was, indirectly, helping the Klingon Empire by doing that.
