It wouldn't be a young adult story if everyone made wise, well thought out decisions.
Harry Potter
I say this with as much respect as possible -- which is very little (if I am honest) -- but do you not understand how fiction works?
If characters in a story -- any story -- reacted how most people would it would be BORING AS FUCK.
The entire point of heroes, or protagonists, or whatever they are called, is that they don't react like normal people would.
If they did they wouldn't be heroes. And then we wouldn't have a story.
If Romeo and Juliet had behaved like sensible adults then no one would ever have heard of them because they would have waited until they were grown up and then run away together. But that wouldn't have made a good story.
If Luke Skywalker had any fucking sense he would have stayed home and not got involved. But then he wouldn't have been a hero. Also he'd have been killed by The Empire. But that's beside the point.
Anyway.
But also remember it is fiction and fiction for kids into teenagers. Don't take it too seriously.
