I'm just pointing how retarded his reasoning was. A oversimplification of the scene coupled with his dismissal of it as if it was an implausibility.
It's not an oversimplification of the scene, it's rather a dissection of it from an objective point of view. If you notice, you're rationalizing a scene with arguments that aren't really that relevant (like Zoro being stubborn). It may seem cold and crude, but the truth is Oda lured the reader with a sacrifice and didn't deliver.
Yes, why do you ask? When it comes to character's death or literary lure to it, I'm on the side of letting them die, no matter how big the name or how it'd good to have them still alive. Of course the exception, as I said before, is when it's used for gag purposes, like Bon Kurei and his "Okamas don't die!" exclamation. How would you feel if those who died in Marineford would get the scenes they had but later they'd be like "lol, fooled ya, we're still alive!"? That's why I hope Sabo doesn't appear alive anytime soon, since it would strip his flashback of its emotional impact.
Yes, it'd be a bummer to not have Zoro around, but the scene could be used much later in the manga and just slap the reader with raw emotion instead of being a pretty scene that delivered too little.
