Dias,

You're not a really bad person. Maybe I don't know the whole story, but in response to this post....

Try to remember you're not who you always will be. These experiences are painful, but no worse than what many have been through. It's part of learning who you are. If you feel you've done the wrong thing, the only thing to do is examine what went wrong and what you might do better next time. You'll never stop learning. You can choose the lessons by "graduating".

Was it neccessary to return the pain the other had started? It may seem apporopriate or due, but what if you'd only restrained him? Just a thought.

Defending your sister is exactly what you should have done. Maybe just a little less returned violence? Be an example to others that there are alternatives to violence. Many are afraid to get involved because they feel weaker than some, but if they knew they don't have to win, only stop the aggressor, they could see their numbers would be enough to make the bullies think twice.

Could you use your position as school guardian to begin a STOP Bullying program?
