One could try to blame Darwin's *Survival of the Fittest* explanation on this one, but I'd have a hard time making a solid case that *bullying* is a higher level of functioning or a superior/stronger vantage place. In fact, *bullying* is quite the opposite. The act stems from a weakened personality attempting to exert control over another...often times trying to exert control OVER someone they fear is superior to them in some way.
*Bullies* find great comfort in transferring their inner most fears onto another...thus the need to CREATE fear by force externally. It is in the act of creating fear in another a *bully* is temporarily defocused on themselves...they feel a temporary sense of mastery and power, which has been deeply lacking in their internal selves. Because a *bully* spends so much time wallowing in their own inadequacies and fears, this temporary "relief"...creating fear or doubt in another...brings them a false sense of comfort.
Children deal with *bullies* every day. This has become a norm of childhood, not the anomaly. And as children, *bullies* also try to instill fear in other children because of a desire to relieve their OWN fears. As adults, *bullies* simply become more sophisticated in their approach...but the end product is still the same.
Yes, behind every *bully* at ANY age, lies a big ol' pile of crap...something a *bully* can spend their entire lives trying to cover up...
