Featured Upright or not?

Hosea.

"The law that was given to our first parents, and the covenant that was made with them, were soon broken by them;

“They like men” (or like Adam)
“have transgressed the covenant” (Hosea 6:7)"

Eve still broke God's command and transgressed.

She had been told not to eat of it, regardless of any trickery.

You notice God didn't just let her slide, but judged her first, before Adam.

So, Eve was part of the transgression.

Adam was a party to bring deceived, and actually could have been more concerned with being his wife where she now was, as opposed to just saying, "I think I'll just wide-eyed openly choose to disobey God. But he did, nonetheless.

And the rest is Historical Facts, also.

Gill BOMB, but worth reading. There is tons more of info on Genesis 3 that lends itself to a fuller and fuller understanding of the O.P., even the conjecture.

"Adam sinned, and his sin is more taken notice of than the sin of Eve; and it is to his sin that all the sad effects of the fall are imputed; sin entered into the world by him, and death; in Adam all died; for he being the federal head of all his posterity, he sinned not as a single private person, but as the common head of all mankind (Rom. 5:12-19; 1 Cor. 15:21, 22).

"Some have thought, that if Eve only had sinned, and not Adam, her sin would have been personal, and only affected herself, she not being a federal head with Adam; but she could not have been the mother of a sinless posterity; for “Who can bring a clean thing out of an unclean?” and she must have died for her offence; indeed God could have created another woman for Adam; from whom an holy seed might have sprung, had he stood.

"But this is all conjecture; nor is it so clear a point that Eve had no concern in federal headship; since though the law was given to Adam, and

Adam sinned, and his sin is more taken notice of than the sin of Eve; and it is to his sin that all the sad effects of the fall are imputed; sin entered into the world by him, and death; in Adam all died; for he being the federal head of all his posterity, he sinned not as a single private person, but as the common head of all mankind (Rom. 5:12-19; 1 Cor. 15:21, 22).

 

God made humans "upright." Yes, that is true before the Fall. Subsequently humanity has been made "sinners."
To be upright refers to being righteous, being honest, being kind and dealing with others with integrity.

But, after the fall, humans have sought out many "devices?" Since this action seems in contrast to "upright" behavior, "evil schemes" seems to be in view. Thus, less than "honest." less than kind, and willing to act without integrity.
