Whats the point of trolling?

Does your life feels so bad you want to inflict harm on random internet denizens? Or were you just born an asshole?

For me personally, I find the action of trolling quite exhilarating, probably to the extent that it's quite unhealthy. Nothing gets me off more than being able to excite the neurological chemical reaction of anger in some shmuck's brain across the world, just by simply typing words on a keyboard with my fingertips. It's like I'm mentally controlling you with my mind, you know what I mean?
