In the first version of creation, every time God created something he pronounced it good. That’s worth noting, especially as we move forward with this. He didn’t say it was kind of cool and let’s see how it goes, he pronounced it ‘good’. So we can assume by this everything, including humans, were originally ‘good’. Not ‘right’ or ‘adequate’ or ‘functional’, but ‘good’. There is a difference between ‘right’ and ‘good’ and if you’re not sure what it is, now would be a good time to go look it up.
How you view the Adam and Eve story will probably shape how you view the whole good, bad thing, but for now, let’s assume God was pleased with what he’d done and all things were good. Being an all-knowing, infinitely intelligent Being, it would seem he’d have a pretty good idea what he was doing.
