Do you think it's bad that I stabbed my bully?
Yes, it's bad. Why did you stab your bully?
I'm tired of his abuse towards me. It has been going on for two years now.
Even though they were bullying you it was wrong for you to harm them like that. You could be in serious trouble with the law for stabbing someone. Next time find a peaceful way to deal with bullies.
I'm sure the police will understand. They won't prosecute me for this.
Stabbing someone, even though they bullied you, is a serious offense. You could be arrested and convicted of attempted murder. Turn yourself in to the police and maybe you can work out a plea bargain with the courts.
