" I did it all for me. Purely selfish. I worshiped the art and the act of
death, over and over. It’s as simple as that. Afterwards it was all
sexual confusion, symbolism, honoring the “fallen.” I was honoring
myself. I hated the decay and the dissection. There was no
sadistic pleasure in the killing. I killed them as I would like to be
killed myself, enjoying the extremity of the death act itself. If I did
it to myself I could only experience it once. If I did it to others, I
could experience the death act over and over again.
