Nope, if anything it's the other way around; Obito had doubts about the path Madara set him on and ultimately couldn't follow through with it as he was shown having major regrets in his battle with Naruto and Sasuke. Madara 100% believed in the Infinite Tsukiyomi and never realised how wrong he was about it until it was too late to do anything.
