to me it looks like Madara ended his own edo tensen why else would he say tell the caster ie kabuto he shouldnt use forbidden jutsu carelessly i dont think madara wants to be an edo tensen he wants to be alive i think Tobi will resurect him because i think madara created him for that reason Tobi has stated that he want to complete i think thats what he means and what Madara said when he was first summoned so it finaly happen that nagato brat has grown its all a big plan and all we seen are afew pieces and him wanting sasuke is part of that plan a young body for Madara to be ressurected in thats my therory
