There's no guarantee Nagato senses Sasuke in time to activate Shinra Tensei. And no, Madara actually cared, since it was him who admitted that Naruto/Sasuke weren't ordinary kids and thus shouldn't be underrestimated. Also, if he had enough time to react to the attack, he would've just sucked himself into Kamui dimension before Sasuke could get him.
