Nathan is the new student at your school. He's short, a nerd, gets only straight A's and he can't defend himself

You've picked on him for the last few weeks and you had a lot of fun! Today, you went too far.

"i-i-i didnt finish your homework..im so sorry.." you snapped and slammed his head against the locker, causing him to bleed and lay unconscious. What do you do?
