Did this badger go into shock?

I totally agree with what you said to "Why bother". I've seen him/her comment rudely on a lot of people's questions ("Why bother" had that coming). I'm not sure if the badger did go into shock The medical definition of shock is: "A critical condition brought on by a sudden drop in blood flow through the body. There is failure of the circulatory system to maintain adequate blood flow." If you didn't see the badger bleeding you might have simply broke it's spine which would result in paralysis. There's nothing anyone could do for that badger and it suffered too much damage to ever go back and survive in the wild. It wasn't you're fault it was just an accident comparable to someone hitting a deer. It probably died shortly after the incident.
