What does it mean to avoid the glorification of violence? What that violence can only ever be bad? Anything can qualify as the glorification of violence depending on the readers perspective. Funny how an examination of when violence is necessary is never a topic but non-violence permeates society.
I don't see what the problem is with violence in a story....within reason otherwise it becomes absurd. As to the OP I think it entirely depends on the story you are telling and it's scale.
The glorification of violence is basically when violence serves primarily an aesthetic purpose or to increase the pace of the story, and the heroes come out unscathed out from a hundred battles. In my recently finished novel, the heroes are basically refugee kids trying mostly to avoid the Dark Lord's mooks.
