Actually Vishnu is the deity of Hinduism, right? Do you believe that there is an evil being in the world named Satan? Could this being also strive to continue to confuse and supersede the true God? There is only one God, and he revealed himself this I believe. He says his name is "I am". Satan, on the other hand thinks he's God and he really doesn't care what name you use for him.

No, I don't. The world is both good and evil.

Do you believe you can escape a police chase? Obviously some are naive enough to believe they can get away, but they never do. If there were Satan and he were trying to supersede God then he is the dumbest villain ever invented.
