I don't get this "murder is bad" stuff here. Riker is murderer by profession: Starfleet expects him to kill the enemy. Yuta is the enemy, even if a sexist asshole from the 21st century might say that she has to be left alive because of her boobs and pretty smile.
"Agony is better than death"? What sort of reasoning is that? Riker is a murderer by profession. He is not a torturer.
I know you have a hobby if disagreeing with me, but seriously?
What you are saying is basically that it's better to fire a fatal gunshot because using a taser is too painful!
Oh, and I sure hope you weren't referring to me with that "sexist asshole" comment, because I certainly never said that.
