Nah, MC was f***ed for this. Sorry, but "it was all just a test" is still a terrible trope, even when it's the MC doing it. Worse than that, he completely shit on a generations-old tradition and the most important vow if his "precious student's" culture and life. I want to give benefit of the doubt to MC, because he's been smart and well written throughout this series, but no; this was actually horrible and tasteless of him.
