"Forget about the type of fruit debate. That is not important. The sin our first parents committed was DISOBEDIENCE!
The first lie told by the Devil was that "God does not want us to become like him. The clever serpent told Eve, God only forbids you from eating the fruit because "God doesn't want you to be like Him.'
That lie is told over and over again. God only makes rules, because He wants to control you. He doesn't want you to be like Him.
That is a lie. God gives us rules. He gave Moses the Ten Commandments. He gives us the Church teachings, all the prohibitions of things we shouldn't do because He loves us and wants us to be like Him."
