That's not right at all. I am a christian. I know the difference between right and wrong and I choose to be a good person. I don't do it with the feeling that I will get a better "seat" then you do in Heaven. I know the Catholic Church preaches what you say and many of them sin all week, atone for it on Sunday and repeat all the sins again starting on Monday. They aren't all like that anymore than non christians are all the same. Being good or bad has nothing to do with being a christian.
The Catholic Church does no such thing.
