James T. Kirk:
Why would a Starfleet admiral ask a three-hundred-year-old frozen man for help?

Khan:
Because I am better.

James T. Kirk:
At what?

Khan:
Everything. Alexander Marcus needed to respond to an uncivilized threat in a civilized time, and for that, he needed a warrior's mind - my mind - to design weapons and warships.

Spock:
You are suggesting the Admiral violated every regulation he vowed to uphold, simply because he wanted to exploit your intellect...

Khan:
He wanted to exploit my savagery! Intellect alone is useless in a fight, Mr. Spock. You, you can't even break a rule - how can you be expected to break bone? Marcus used me to design weapons. I helped him realize his vision of a militarized Starfleet. He sent you to use those weapons, to fire my torpedoes on an unsuspecting planet, and then he purposely crippled your ship in enemy space, leading to one inevitable outcome: the Klingons would come searching for whoever was responsible, and you would have no chance of escape. Marcus would finally have the war he talked about, the war he always wanted.
