adam and eve big mistake

Adam and Eve if they can only see how disobeying God has effected humanity the forbidden fruit opened up so many things murder, lies, homosexuality not to knock gays but God ment for man to be with women so i have to ask if they never took a bit would have Jesus gave his life would Emmett Till never lost his for whistling at girl Malcolm and Martin to JFK would New Orleans and Haiti be ok if only they saw the towers fall maybe they would listened cuz are past dictates are future so even tho im responsible for myself i think what if? Just a thought that things could be better if two people would have obeyed maybe life could be better
