"but there are far too many people out there who would love to harass someone for no reason at all."
I find it very interesting you conclude, "no reason at all", because there is a reason, but unfortunately most people have not learned to see the reason, why some people behave this way towards others. When someone harasses someone else, there is always a reason, and that reason is always some form of personal gain from the harassment.
In a way, I find it both good and bad that a lot of people can't think of a reason, why someone would behave this way towards other people. Its good, in that most people clearly don't think (and so don't behave) this way towards others, which is very encouraging for all of us. But unfortunately is also bad, in that if more people learned to think like this, then fewer people would become the victims of this kind of treatment.
Everyone who continuously harasses, manipulates or ruthlessly exploits other people, for their own gain, is demonstrating a very strong sign of a cluster B personality disorder trait. One event of this kind of behavior, isn't enough to predict a person is this way, but a continued treatment of others by harassment, manipulation or ruthless exploitation, is a clear indicator of
cluster B personality disordered behavior. But their behavior is not the reason why they are this way.
Here's a quick cut and paste from a previous post...
"The world will never change until everyone worldwide realizes that people who constantly seek power over others have a recognizable cluster B personality disorder. All cluster B personality disorders are ultimately driven by fear. And the ones with the disorder constantly seek to control that fear and control everyone around them based on their fear. (There are multiple fears, two examples are lack of attention and another is fear of lack of power. (There are also other fears). The attention seekers want more attention (they were deprived of parental attention as children. The ones who want power seek to prevent anyone ever having power over them again, the way they were treated unfairly as children)."
Cluster B disorders are only a minority of the population, but thought out our lives, we all meet multiple examples of these kinds of people in our lives. (To give an indication of the kinds of numbers of these people around, for example, its estimated that over 80% of people in prison have some form of cluster B disorder. Also there are many cluster B disordered people who are not in prison, but continue to treat others around them badly. (At times horrifically). Some are even in high positions. (They seek positions of power over others, sometimes relentlessly seek high positions of power over others). Also some of these people can be extremely convincing, as they spend years learning how to manipulate others. Some are almost like they are acting a role as they manipulate others and they can get very good at it).
