Do whatever you want, but know this: You completely missed the mark on almost everything you said.
First, I never said I hated Shy. I said I hated the cliche of an all forgiving MC and why this philosophy causes more impunity than justice. You simply read into it wrong.
Second: YOU said that edginess rarely works out and I proved you wrong with all the examples I gave. The point was to prove they were successful and can work, not they were morally correct. I showed that brutal and gruesome characters in a storyline that is not based on some linear "good vs evil" base, but instead on a gray clash of interests and ideologies can work extremelly well. So what if it's about the scums on earth? What if people criticize it for the shock value? None of that will change the fact that these series and games are praised both by critics and gamers (both on plot and gameplay\entertainment) and presented characters that certainly will be immortalized. I would love to add The Last of Us in here too. Known as one of the best stories ever created where such thing as mercy is almost completely crossed out of the table. My point was defended: Edgy sells and edgy with dept sells spectacularly.
And lastly, you tried to limit this discussion only to this manga, but I'm criticizing something that appears in several works, not only this one. I agree that the villains here are also victims and IN THIS CASE they might deserve redemption, but Shy's approach and beliefs cannot be applied to every single case. She (and anyone else) can't and shouldn't go around trying to save and redeem everyone because some villains either don't deserve it or are not intrested in it. That would be insane and pure injustice. You praised Shy for being faithful to her principles no matter what she went through? Well so is Levi, Ruvi, Alucard, Kratos, the Punisher, Trevor Phillips and all the others I listed. The difference is that, although some might believe in the same ultimate goal, their principles are very diferent.
So I'll stick to my previous statement. I believe edgy and mercilless character are better. If you think otherwise, it's your choice and opinion.
