in my opinion they didn't need to. sakura had the Byakugō no In seal activated and as such was using her Mitotic regeneration as such as long as that seal was active and as long as she had the proper amount of chakra she was technically just as Immortal as madara

so instead of saving sakura's life Naruto and sasuke should have focused solely on madara and used the six paths chibaku tensei on him. had they done so they would have been able to defeat him right then and there

and saved her life after touching him with the seal

people say she was stupid but out of those three her actions were the most tactically intelligent as she did exactly what she was said she was going to do. and that was act like a decoy
