Your Star Trekiology verse of the week.
Verily, Captain Kirk tells us:
"But the instinct can be fought. We're human beings with blood of a million savage years on our hands. But we can stop it. We can admit that we're killers. But we're not going to kill, to-day. That's all it takes. That we're not going to kill, to-day."
