It was inevitable.

As a student of religion I have not encountered what exactly this forbidden fruit was. What I do know is that they could not obey all Gods commandments unless they became mortal. Mortality is somehow necessary to have offspring and was linked to partaking of the tree of knowledge of good and evil.

Before anyone says that the forbidden fruit was sexual sin, must I remind them that Adam and Eve was man and wife lawfully wedded by deity himself. Besides, the very first commandment given them by deity and hence probably the most important was to multiply and fill the earth.
