If it was a sacrifice like you clowns are claiming for damage control, then Oda wouldn't have drawn Zoro actively blocking the attack for several moments with swords. Reading comprehension 101 error
Only headcanon here is yours thinking anyone is claiming that Zoro would've survived the entire attack.
