If you break someone's neck can you go to jail for that?

Yes,

you would go to jail, it could be considered assault, battery, or even attempted homicide. unless you have a valid excuse like you did it for self defense, but then again trying to convince and judge and jury that you had to snap his or her neck to get away would be hard to defend. depends on the circumstances.

hope this helps :)
