Nagato would have caught all of Junchuuriki very long time ago with it. Nagato's only reason for living was as a vessel for the Rinnegan. Nothing else. All he had to do was to be convinced of Madara's truths and give his life in exchange for Madara's.

Why'd you think he was unaware that Rinne Tensei kills no matter what?

Still don't have a reason for that. Madara could easily teach Nagato Rinbo via Obito. Wasting a weapon which Jinchuuriki have no way to deal with.. Really dumb, isn't it? Because of lacking of enough power to defeat Naruto, Nagato was forced to have a conversation with him, leading to Nagato betraying Madara.
