Give a SH a 0.00001% survival chance and they will survive lol
You could drop a Nuke on Zoro after he took Luffy's pain and he would stil be alive.
Oda said no matter how desperate the situation, the SH's won't die.
First, Sanji took much more damage than Zoro at this point.
Second, it was Zoro's moment, not Sanji's.
If you think it makes sense then you also must agree that Pell surviving the Nuke made sense right? Because it's always funny how Zoro fans say Pell surviving the Nuke was BS, he had plot armor...
