We're debating whether or not leaving a civilian behind to be tortured and possibly killed is acceptable. There should be no fucking debate at all about this kind of treatment.
Yet here we are. Thanks Discovery!
This isn't the first time that we have seen starfleet officers make questionable or outright wrong decisions.
Considering Mudd was pumping starfleet officers for information to give to the enemy and then allowing those officers to be beaten to death so that he could live without being tortured is pretty despicable. Nah, he can stay where he is.
