Star Trek has generally not presented the philosophy of 'turn the other cheek', occasional Picard moments aside. From TOS onwards, Starfleet has been happy to fight and kill when it considers it required. Check out The Savage Curtain - Kirk mocks Surak for trying a peaceful solution and starts sharpening a stick, and the rock monster guy even calls them out on the fact that their survival methods and outcomes are indistinguishable from those they describe as 'evil'. Trek often went with the admirable theme that enemies are just like us once you get to know them, but almost exclusively this was done when they were winning or in a position of power and they showed mercy - Balance of Terror, Corbomite Manoeuvre, Arena, I Borg, and when they are losing, or face danger, all seems fair and they kill without a second thought.
