While the difficulty of "Sekiro: Shadows Die Twice" is clearly important to the game's biggest fans, it's probably more important that the people who choose to play "Sekiro" are having fun. Some players will certainly be ready to rise to the challenge, but there's nothing to be gained from shaming players who want to use cheats on their own terms to make the game less demanding, and ultimately more fun for them to play.
There's certainly no honorable or "right" way to play the game, and playing on your own with cheats isn't worthy of shame either.
