Yeah his whole moral re-evaluation is draggin' this season down for me. I expected a one-kill-per-episode quota outta the guy!
I like angry knife wielding, wrap-you-in-plastic-and-cut-you-up Dex.
You know, though, in actuality a character like Dex would most probably display even more horrific tendencies than shown. Be it the homoerotic Dahmer aspect or the cannibalistic Gein aspect. You don't go into a routine of systematically cuttin' up humans without taking a next step. It's about power over the victim. So I've always thought his method was TV Tame. Dude would be gobblin' testies or makin' skin shoes or sumthin', if not blowing up at and taking out aggression on innocent people.
The family angle is interesting though. The "Iceman" Richard Kuklinski was known as being a devoted and loving family guy at home. He killed a guy on Christmas night on the auspices that the victim owing him money disturbed his time at home with his wife and kids.
