Do you remember an old Twilight Zone episode with Dennis Hopper in it? He portrayed a Hitler wannabe and was failing until the "real" Hitler showed up "to show him the way". Long story short, Hopper's character was finally killed and the "real" Hitler moved on to spread his slime another day. That's how these monsters thrive. After the BTK P O S is killed, there will be another one that'll crawl out from under a rock to spread misery. And the hell of it is, it won't end until we are all dead and gone, or until the Second coming, whichever comes first.
Don't remember that one but sounds like a classic. When are we going to learn there are lots of really bad people out there?
Yup!
Too bad Bill Mumy couldn't "WISH HIM INTO THE CORNFIELD!" ;>
