see, there's a common misconception. just because he didn't get sexual pleasure from his acts doesn't mean he doesn't fit a certain psychological profile that might be predisposed to this kind of behavior. i've been obsessed with serial killers for the past 8-10 years or so and am familiar with Kuklinski and i wouldn't say there's anything more or less interesting about him than any other serial killer with the exception of how long his run lasted. what you might or might not be aware of is that his younger brother, Joseph, was convicted of raping and killing a 12-year-old girl when he was in his early 30s- these men were clearly raised in such a way that their genetic predispositions to be violent were greatly enhanced. the differences you pointed out between him and other serial killers are small, mostly insignificant differences. there's a reason he was predisposed to murder and we, as a society, should be a little more concerned with figuring out what exactly that is than exterminating these monsters. why you wouldn't want to find some answers is beyond me.
and the things this guy did pale in comparison to Dahmer's apartment. i've seen hundreds of photos, if not a couple thousand, of serial killers' work and none of them have made my skin crawl like the one taken in his apartment's bathroom where they found a half-gutted person laying in his bathtub, rib cage fully exposed and a look of absolute terror on their face. Kuklinski might have had the numbers, but Dahmer had more than enough brutality to make up for it... how they're similar and what made them who they are is what we should be trying to understand, not how to most-efficiently execute them.
