I don't agree actually. While plot armor will probably result in us going unharmed, it closes some opportunities, and might not be that beneficial.
Caution is, of course, the best choice of action, but I do wonder what kinds of opportunities it closes. I mean, nobody saw our face yet behind the mask, and even if they did, do you honestly believe that our father would think twice before going for the kill? The man runs a semitheocratic dictatorship, and if that was not enough, he was shown as perfectly willing to brainwash his son into becoming his ideal vision of a hero.
And besides, announcing that we are/have The Hero would most likely result only in everybody trying to kill us even harder.
Just wishing to know the public opinion and ready to be proved erroneous.
