E is not making the assumption that we are judged on an absolute scale of
perfection, but he is saying that a superior or more determined soul (G's
soul) may have changed his striving to be good in his environment.
Let E = Esau and let G = Avraham Avinu. So putting this problem in concrete
terms, Esau is saying that if he were given Avraham's soul he would have
succeeded in his environment, and he would not have become an evil person.
If one can show that Esau's argument is fallacious by a logical proof only
with the use of basic axioms of Judaism then one has solved this problem.
