Recently all my questions were answered. You see, I came upon
the book The Sociopath Next Door, by Dr. Martha Stout, and
everything snapped into sharp focus. A sociopath is someone who
has no conscience, who is incapable of feeling empathy or sorrow.
It's not a truly evil trait, it's simply a genetic disorder, like being
color-blind. An alarming number of people (1 in 25) are
sociopaths. You are one of them. You, sir, are a sociopath. The
reason you can do unconscionable things is you have no conscience.
And when I realized that, I stopped being angry at you.
