I suggest this (however loosely) based on motive as displayed throughout the series: The hunter killed for fun and to keep his mind young. The 'artist' was bored and wanted to create art reminicent of her father's, if I recall correctly. One killed for stress relief, delusional grandeur of glorified memes and so on. Makishima took life on a complete whim. I'm willing to believe that he truly didn't care if Akane picked up the double-barrel and blew him away (though he likely doubted it). All of the other latents killed in private, or around people that would keep quiet; I could argue not because they wanted to avoid problems with the law (solely), but because deep down, intrinsically, they knew that what they were doing was wrong. And that is what, from my understanding, makes crime co-efficient rise: the desire to do wrong and the awareness to acknowledge that it is wrong. If Makishima views human life (maybe even his own) as insignificant on the level we do when swatting a fly - as a reflexively disposable thing - it is not as much of a stretch that this (series of events) is his more sophisticated version of 'a six-pack and a bug zapper on Friday night'.
With that flimsy logic, I would conclude that Makishima is possibly neither insane nor broken, but... "incomplete". The nebulous feedback loop of human biometrics that Sibyl uses to assign hues and coefficients does not register this man as would be expected. I don't buy his spiel about Sibyl seeing/uncovering the soul, though. Just because he says it doesn't make it true.
