Great that this has made it to the front page of Hacker News.
So sad that this happens. I changed schools 5 times and only 2 of them had no bullying. It's true that it changes you. There are some good resilience changes that happen, but there are bad changes too.
...Unfortunately I think it is the human condition to want to have power over others. It would be awesome if there was some way to fix this, but we are all a bit broken I think.
