1. nagato don't need to get close to itachi
2. kakashi died out of chakra exhaustion as a result
3. katsuyu is a special summon from a KAGE/SANNIN, katsuyu can heal who ever it touches via the chakra of the most skilled medical nin of all. comparing it to susanoo is BS.
4. nagato can spam shinra tensei, but itachi cannot use susanoo that long
5. itachi even inside susanoo cannot block GRAVITATIONAL PULL/PUSH.
answer this with logic..can you block gravity with a shield? lol
1. Yes, since

is huge close contact isn't even necessary to seal him with Totsuka. Moreover Itachi can get close no Nagato.
2. Not as a result. He simply died of Chakra exhaustion. Naruto didn't took heavy injuries from it either. The one that blew away the frogs was a stronger one.
3. It wasn't about healing. Just beeing inside of Katsuyu protected the most villagers from receiving heavy injuries. Shinra Tensei isn't
that strong.
4. Itachi used it for ten minutes after he already used Amaterasu four times and extinguished it once. Not to talk about the Tsukuyomi that got broken. Furthermore Nagato definitely can't spam it, there's the fatal interval that at least lasts for five seconds. The more power he puts into it, the longer the interval becomes.
5. Obviously I can, since six tailed Naruto didn't just block Shinra Tensei but threw it back at Pain. To concentrate chakra in her feet was even enough for Tsunade to withstand a smaller one. So yes, with Yata no Kagami, which is said to block
every attack Itachi definitely could block Shinra Tensei without much effort.
Now it's your turn; what intends Nagato to do against Itachis Genjutsu? Or are you one of those ho doubt that Genjutsu works on Nagato? :'D How will he block Yasaka no Magatama, which is a spirit weapon, too? What will he do if Amaterasu hit's his eyes during the interval? Or what whill he do if he kills one of Itachi's Karasu Bunshin with Shinra Tensei & gets hit by the Shuriken the crows can transform into?
