Morally, it horrifies me that people can behave in such cruel ways. On the other hand, I was a soft pile of shit until they made me realise, no - life isn't perfect or fair. It is what you make it and even then, things don't go completely to plan. They helped me mature, grow up and learn just how strong I can and have to be in order to face the world.
Without bullies, I would let people manipulate me. Walk over me, even. I was too trusting and kind for my own good when I was younger.
But now I know that I can't believe everything someone says. That not everything they say is true or even relevant. So in a way, bullies helped me improve myself.
It's just a shame that they can bring such destruction to others.
Actually bully's have taught me a lot of stuff. Like don't take shit from any one, and become smarter, faster, and stronger. They're just culling the herd after all.
