Why do Catholic people idolize the pope?

really.. jesus was supposed to turn the church to peter but the pope isn't peter. The bible is considered the words of god transcibed then why do the catholics feel that they have to revise it, such as throw out or reject whole or parts of the old books of the bible at the council of nicea.Damn the catholics think their poop don't stink. Please give me some insight someone because i want an educated descisions.
