Perhaps, they don't have partners or children, maybe it is part of the reason some people are so aggressive.
That's possible, but I've read a few horror stories of closest people being the bullies just to feel power, they still got found out eventually.
I can't imagine a "happy soul" who takes pleasure in attempting to inflict some type of suffering on others intentionally
I can't imagine a "sad soul" doing that either :S Wouldn't they know best what it feels like to feel down and not want it for others? I really wonder if it's the angry ones or some other emotion or lack of it that creates those personalities.
due to the childish and immature nature of it - yet coming from an adult.
A lot of trolls could very well be teens/young adults with brains that haven't finished developing, hard to tell online who the troll really is. If it really is an adult, it's probably someone really bitter about their life and how "unfair" it is compared to others. Just guessing.
