I'm starting to think the latter part is what he actually enjoys. His abduction and killing methods are so mundane and...dispassionate? He's really separated from the act of murdering (for the most part, until he stabs Sachiko). Spraying a beaten unconscious Kayo until she freezes to death and picking her body up later, or smothering another girl with charcoal briquettes in a bus, or whatever he did to Hiromi and all the other children.

It's the framing others part that he truly likes. He was present for when Satoru got picked up by the cops, smirking, taking it all in. That's the compulsion.

The game is framing someone else so completely that suspicion never falls on him, and being there when the person he framed gets caught is the sick pleasure that he basks in. It's almost like the kidnapping and killing children is just the means to an end. The murders are secondary, the framing of another is the actual goal.

Sachiko and the professor both believe he sets a pattern before moving on. It seems to be getting someone else caught. When Sachiko spoiled his latest plot in the present, he switched to framing Satoru for stabbing and arson.

I realize I said it about three times in this post, but it really is starting to build up that way.
