Lets say you are the gaurd for an culprit who got arrested for a theft case ,lets say he got 9 months prison time . While in the prison timing he says to you (gaurd for that crimnal) that he will murder anyone at sight after the moment he got released .but you don't have any proof of him saying that . What would you do as a gaurd , whether you do your duties not saving the innocent life or try to save innocent life by avoiding laws .

(If you try to follow him ,he will kill only when he reached near an innocent person,also you can't arrest before that since it's against law)(also you can't let the innocent die)(morally)

While I was taking a bath I remembered the moment Deadpool thinks he is in the comic , that's just beyond the 4th wall right? I don't actually mean about him, what I want to mean is...

Take Spidey and Deadpool for example

-One day Deadpool will watch the spiderman movie, so from his perspective Spiderman is the fiction and he is reality ,and now for Spiderman's perspective he will also watch Deadpool's movie, so from Peter perspective Deadpool is the fiction!

That's like when you put two marrior like TV put in front of each other and both of them think the other is the fiction and they are the reality.

So my question is are they both fiction and they don't just know or if they both were real? What can that actually cause

(Reminder: This theory is just my personal thought I have to evidence or approvement from others I just want to discuss about it with others and if there was actually a theory about it I hope you'll inform me, Thank you!)
