Agreed. They're a bunch of insecure wretches who have major
inferiority complexes.
But they don't seek help. Instead, they try to alleviate it by
taking it out on people whom they perceive as 'weaker' than them,
in the process 'reassuring' themselves that they are indeed
'superior'.
I've been at the receiving end of bullying - both physical and
psychological - as I was growing up.
I can agree that whether a person turns out into a bully or not has
a lot to do with his upbringing. For all we know, the bully may
himself be bullied or abused at home by his parents.
If that's the case, it might be somewhat understandable why he may
end up as a bully, but it still does not in any way excuse his
actions. A bully with a troubled past is still a bully.
