To write about a personal experience.

This story made me feel sad 
However, the purpose of this story is to reveal the cruelty of our world and the protectors who help and protect children
The quote, "Nobody wants to be told what they're doing is wrong" is true. Sometimes, we never accept when we're wrong.
"and you see the terror" represents that nobody cared until something had to happen.
I'm sorry I couldn't get much from these quotes. This topic is a bit tough for me sometimes and I'm just doing my best to help.
Answer:
there's no idiom

3. It emphasizes her discontent with her situation
I hope this helps!
