Terrorism is just one end of a whole spectrum of cruelty humans inflict on each other everyday. There's blowing places up ,hijacking planes,or mass shootings to making someone feel worthless and everything in between. Is child abuse by the parents terrorism? I'd say it is. Would it be glorification if a movie tried to understand why the parents are the way they are ? Would that be a justification of what they did ? Depends on the movie and what kind of narrative it comes up with. Terrorists don't exist in a vacuum. Its very important to understand why people do what do if you really want to curb it.
