Yes. Its like all other bijuus try to control the jinchuriki. Same way, Juubi is trying to take control over Obito or has already taken control over Obito.
Many can not accept anything negative about their fev character .... Its bit like what Itachi said: "People live their lives bound by what they accept as correct and true. That's how they define "Reality." But what does it mean to be "correct" or "true"? Merely vague concepts... their "reality" may all be a mirage. Can we consider them to simply be living in their own world, shaped by their beliefs?" ........
