we know Pein wants the kyuubi to make weapon and destroy the world cuz he think he is god.
but what are maadara intentions with the KYUUBI?
1. World domination
2.destroy world like pein
3.ultimate power
4 revive uchicha clan ( never happen)
5.revenge against konoha

what do u think maadara wants with the kyuubi or even if he wants it at all?

The second thing why did he lie about summoning the kyuubi on konoah 15 years ago, Jiraiya and itachi both say he did, could he deliberately deceive

sasuke and for what?
