You're mistaken in a) that Madara didn't have anything to gain - actually, he gained Obito's loyality to the plan, since he needed a successor to move the plan forward, which wasn't possible with elderly Madara barely sustaining his life b) that he wouldn't use evil methods - Madara has never hesitated to use them, since, according to him, his Eye of the Moon Plan standed as his main priority, and any sacrifice or evil deed was for the common good.
