I started writing, but eventually got to thinking "I've already written this before, I think". Sure enough. Okay, second go around.
The way the story goes is that a choice was offered along with a lie enticing the breaking of a rule given. The story given by a tempter said the fruit of a particular tree had special powers to open the eyes of the one that would eat it, enabling them the ability to differentiate between "good" and "evil". The one tempted had been advised that eating it would bring death. Whether by the defiant act or by the characteristics of the fruit not being clear, the tempter could direct attention to the fruit itself rather than the act, as the "risk". A bit of misdirection challenging the argument of death with a claim that such "death warnings" were selfishly made to keep us ignorant, and a claim that the fruit offered an ability beyond our nature worked. So successful was the "lie" that generations upon generations would repeat, believe, and promote it. Today people still think they can somehow determine good from evil, yet they have nothing more to go on than their likes and dislikes. By consensus, and popular opinion they define their likes and dislikes beyond simple individual preferences as "established" evil or good. Through laws, creeds, systems, "inspired writings" and dogmatic tomes we establish our definitions of good and evil.
The story of "you will not die" remains the most heavily entrenched belief, as nearly all religions and many philosophical reasonings offer continuing life, even continuity of life beyond physical death.
My words, for those that like them are "good".
My words, for those that don't are "evil".
My opinion? I prefer not to form one. I'm not qualified.
I only know what I like and dislike.
