You left out pleasure and fear. Most serial killers receive sexual gratification from their kills. Many homicides are the results of the perpetrator's fear of being caught at committing a different crime, burglary, robbery, rape, etc.
Yeah, but pleasure from killing is a secondary result, not usually a prime motivator, I'm thinking the motive in that case would be more along the lines of Control. Like serial rapists, for example the pleasure the rapist gets is secondary to his primary motive for the need to control/humiliate the victim. Fear could be its own category, but I'm not sure if it would make me more sympathetic to the villain. Because they are basically acting out of cowardice.
Like framing your rival for murder to get him/her out of the picture. Then you're free to get the girl/guy.
That's sort of more the motive I was thinking, and it would fall under jealousy--all for a sick twisted love. Also, this topic makes me think of the movie Scream. (Yeah I know silly teen horror flick) But the motive really got to me...he killed his girlfriend's mom, because her mom had slept with his dad, and the affair tore apart his family. The killer's own mom flew the coop as a result, setting off the spark that turned him into a killer.
I thought that was a pretty strong motive, which would def. fall under revenge.
But yeah it's difficult if you want to write a psychopathic killer and still have him/her have a motive that
makes sense as another poster said. (Because in real life motives can be quite flimsy-but I don't think this would fly in fiction) And also you look back and see all the clues you missed that lead you to this motive, while you smack you forehead, thinking, ah, i should have seen that coming.
I think that if the motive is strong enough, whatever it may be, it can garner perhaps not sympathy but a new understanding on the actions of a killer. I dunno the "crazy" killer who kills because of paranoid delusions of "he was going to get me" seems a bit weak to me. Just like ending the story with "oh, he was psycho/crazy/etc..." Because, yeah, granted psychos have a different emotional q than regular people, they may not feel remorse, but they still have drivers and reasons to do the terrible things they do, in fiction anyway. End rant. lol
