@Jason of the Mangekyou, Madara only stated that the whole show with kidnapping Rin was his own plan. Plus, he explicitly mentioned he would've made Kiri Anbu kill Rin before Obito's eyes if Kakashi hadn't happened to kill her first, so it's obvious that Madara wasn't going to finish up the plan with Isobu's rampage, his main objective was to show Rin's death to Obito and thus corrupt the latter.
