Witchcraft and wizardry certainly have their appeal! To be in control all the time would be nice. However, we cannot be in control. Through witchcraft, Satan offers much, but like all his offers and promises, they are illusions and lies. They can only bring happiness for the short term. Your life on earth will only be for a certain amount of time, and then you will have to come to grips of where you will spend eternity. To finally answer your question, I would not become a powerful witch ever. There is no such thing as a white witch, all witchcraft is bad, and sooner or later I may get mad and be tempted to seek revenge.
