From "Logan's Run: Crypt (#1.7)"
But don't you see, Doctor, what the murderer did was vital to his purposes. The murderer believes, just as you all believe, that your particular branch of knowledge, your special skill, is the one most important for the reconstruction of the world. And what was Mr. Lyman? Merely an inferior obstacle. The killer removed it.
That's horrible, Rem.
On the contrary, my dear Jessica. To the murderer, it was a logical justification.
Not logical, Rem - pathological.
