In "The Man Trap," Dr. Crater and the creature in disguise as Dr. McCoy make the argument that the creature is not killing out of malice or evil, but rather simply using its natural abilities to survive. They suggest offering the creature salt openly and without deception, as when its need for salt is met it has no reason to kill. This seems confirmed in the fact that Dr. Crater, when providing the creature with salt, was left unharmed.
So, my question is... was it the right or wrong decision to kill the creature -- and thereby cause its species to be extinct -- given the circumstances? Given the Federation's philosophy of respecting all life, no matter how different from our own, would it not have been a more appropriate decision to find a way to meet the creature's needs and avoid future harm? Or does the threat the creature poses when deprived of salt justify the action they took?
