also I may just add the despite being seen as "insane" thrill killers are actually almost always sane, the act is deliberate and planned before hand.. many spree-killers also plan their rampages well in advance, making it difficult to see if they are truly "insane" by definition or not..

many thrill killers feel powerless or frustrated and target a specific victim type to feel powerful, hence they employ a lot of sadism in their killings - it tends to be about power.

I dare say the idea that thrill killing has no motive is false, it does have motive.. just not one that is easily seen until the aftermath.
