I think you strike the nail on the head here, and in the process touch on something that I have noticed: "Trolling" is about power. People do it because being able to push somebodies emotions one direction or another lets them play with that person like a marionette. Making people upset is a power trip for trolls. It would not suprise me if many (not most by any means, but many) trolls are in fact psychopaths who are 'practicing' in a way. Running low-risk experiments on how to control people.
