Edwin pokes embers of a dying fire with a branch before speaking.
“I didn’t always live in a cave, you know. There was a time when my name was synonymous with genetically modified organisms. But I also worked on behavioral adjustment for military applications.
Originally, the inspiration for Toxo came from my own, uh, defects… You see, in all other things I was rational to a fault, and yet I could not control my sexual urges. By day, I was completely normal; by night, I was a monster of twisted perversion.
It was a moment of self-realization that I could reproduce *this*effect in others. Toxo ties arousal to aggression, so it makes a rational man a slave to irrationally violent desires. Of course, I had no idea Toxo would develop a life cycle for spreading in the wild."
Edwin sighs, “So, between creating the parasite that has ended civilization, and my predilection for child molestation…”
He reaches to loosen the gag on his captive victim,
“There, that’s better… Which do you think is worse?”
