Of course not. There is no need to “Have To” dedicate yourself to him. I do know that some say that you have to dedicate yourself to him. They must have gotten that idea from the whole christian thing that christians have to dedicate themselves to god. In this path, you are not forced to dedicate yourself to Lucifer. It is a choice. If you are truly going to follow him, it should come from the heart. Do not just dedicate yourself to him just to do it.
