I think we do not understand 'perfection' in the same way that God understands perfection.
How can there be two different kinds of "perfection"?
Perfection implies two things: a purpose and a tool for the purpose.
A fork is perfect for eating peas but imperfect for eating soup. The purpose and the tool much match.
The fork, by itself, is neither perfect nor imperfect.
People are not, of themselves, imperfect. They are suited for or not suited for particular purposes.
If God wanted humans to understand that eating fruit from a certain tree was "bad" it strikes me as passing strange that he
created them unlike Himself "not knowing good and bad." The result was that Adam & Eve were missing an important part of their humanity.
They had the craving "to be like God knowing Good and Bad" but not the nature.
