Sasuke showed that he cares for Naruto ( he saved him with Susanoo from Omyoudon , he shielded him with Susanoo when Obito stuck a Bijuu Dama at Minato and he was willing to save him and Juugo from the 4 Bijuu Dama ).
But you might be right on this point.
Well Kishi is known to alter his own set rules like how to gain MS , you need two MS to use Susanoo etc...
So at this point of time , i won't be surprised if he do it again with Izanagi.
You seem to be misunderstanding of how the jutsu works. Let me explain it to you.
Izanagi makes the wounds look like dream when its activated

, however when the jutsu is not

as result, the injuries of the latter are real

hence why the scratch in Danzo's left arm did not become an illusion when Susanoo scratched him.
Danzo released the Izanagi and hence the scratch remained even after when he activated it back.

Izanagi redirected Danzo to the point when he got the scratch from the Susano'o. That's what I'm saying, the jutsu only works for the user of Izanagi, and so Sasuke cannot use that Izanagi to save Naruto because Izanagi will only redirect Sasuke to the point where Sasuke activated it. Naruto will remain the same as shown in the current chapter.
Hence why Obito's injuries did not heal even with Izanagi activated

although he survived the death from the 6 billion explosive

and that was because he activated Izanagi.
Obito, at the start, tried to Kamui the blast and in that process his arm got destroyed. But then afterwards, he used Izanagi and get himself caught into the blast without doing anything. This image,

only proves that Obito used Izanagi at this point of the situation.
Then why he could teleport Naruto and Sasuke countless time in this war ?
Minato teleported Naruto and Sasuke only twice.
One, when Juubito grabbed them both with their faces. Since Naruto made a contact between the two through Kyuubi's chakra, Minato was able to connect his own chakra with the kyuubi's and hence could teleport him.
Two, when the four Juubi bijuudamas were about to destroy everything inside the barrier. Everyone except Juugo and Sasuke didn't had the shared chakra which Naruto shared. Plus Minato and Naruto directly made a contact of chakra and hence Minato could teleport them.
Why he could teleport the Kyuubi when he was on top of Gamabunta ?
Minato was in contact with Kyuubi through Gamabunta.
And Minato already said that he needs contact with the target, either physical or through his own chakra.
Take a look.

What do you see?
From this I analyzed that when Minato found the Kyuubi, he jumped over the kyuubi, standing on him and then summoned Gamabunta. A direct impact out of nowhere. Plus he requested Gamabunta to hold down the fox so that he can gather enough chakra to teleport Kyuubi and the blast. If this is how the sitaution went, then Minato already connected his chakra with Kyuubi. The manga shows that way. Gamabunta appeared directly over the stomped Kyuubi.
But if my analysis is wrong then Gamabunta and Minato must have jumped over the Kyuubi because of Gamabunta's jumping ability.
In any way, he connected his chakra with Kyuubi through Gamabunta.
And as I already said, Minato's jutsu depends upon Minato to whom he wants to teleport either along with him or only the target.
Whereas Izanagi doesn't takes into consideration whether which wounded part of the user must be healed or not.
Can you explain me how Madara did survive against Hashirama ?
Plus i said that if Kishi choose this way , then he has to come up with a lesser restraint otherwise EMS users would be invincible.
I believe that Madara didn't use Izanagi to avoid his death. Otherwise, like the illusion fades away, he should have had faded away from Hashirama's eyes. But he didn't means he used something else to avoid his death.
What I believe is that Madara used his MS technique which he never used while battling against Hashirama. That technique might be to avoid a fatal blow. Take look.

^^^ This image shows Madara's EMS in the last panel. But if you consider this whole page, we would say that he used his EMS to copy the handsigns, Hashirama's was forming.
But check out the next page.

The time when the story was ending.
Plus the important thing, Madara didn't even activated Sharingan against an opponent stronger than him. What could be the reason? answer : I believe that in the previous page, he used his MS technique on Hashirama to make him convince that Madara died by his hand that night. But Madara escaped while Hashirama remained under that impression. Madara didn't use any clones, otherwise Hashirama could have found it. Madara wanted to make it seem real. And that's how he used his trump card, another MS ability, in this final battle.
It was Naruto and Tsunade who saved Shikamaru ( Naruto activated the Kyuubi cloak on him ).
Yeah Naruto helped him as well, but still Naruto was trying hard to recover Shikamaru as fast he could. Thanks to Tsunade's tap on the forehead. At the same moment, the whole forcing chakra from Naruto rushed through Shikamaru's body and helped him recover fast. Tsunade was the main who saved Shikamaru.
