Regarding Obito, yeah, that's true, but Danzo already couldn't avoid his death, unlike Madara - as I already said, he had several mortal wounds from Sasuke's Chidori Sharp Spear, and Izanagi can undo only the injuries received during its activation, those infliced before it would stay. Madara's Izanagi was something different (since it was sealed in the eye beforehand) and still couldn't cancel out all the wounds received by Madara in the VoTE, prompting him to use Hashi's DNA to heal the rest of them.
