You know, it's funny. Trolls might not be who they seem to be online.
Some individuals feel like they have to prey upon other folks because they want revenge on the world that made them bitter. Perhaps there were countless people in a troll's life who betrayed them, harassed them, treated them like they were less than human. After all the years of being toyed with and picked on, something changed? It's like the person who acted as a doormat for so long had become the one trying to step all over people. When you chisel at a person's psyche, break it down, maybe even destroy it, grind it into dust. What do you have then? What is left after someone is stripped of their morality? Is it a bitter human? Cold? Do they feel unwanted? Maybe they feel like they're approaching their end, and want to see innocent people suffer. There might just not be anything left in that person's life that makes them happy. Next time you see a troll trying to act like a human, please, treat them like a human.
