Uh... that was just one dude, and me TBH, half-coherently digging his heels in on the Nagato issue. The only other two people who commented were more generic 'war crimes are bad'.
I have never liked or understood this mindset of 'reset is cheating'. If you find that you've made a mistake/made Nagato OOC, then the logical course of action is to fix it. It's like writing an essay for your college class: If your professor hands you back your paper with comments and gives you the chance to implement them and re-submit it for a higher grade, why wouldn't you do so?
The more of the story you spend on this subject, including the fallout, the more this highly-charged environment will remain. The thread and story will no longer be about Sara's War. It'll be about Nagato's actions. Whatever chance there was for treating the tensely-debated, very polarizing IRL subject with decorum is frankly long gone. We've already gotten one person who's using things as an excuse to start a fight...
You're the author. You're only limited by your imagination.
