The reason why I would argue Faust over Frankenstein in this case, is not so much over which one showcased the "human condition" more accurately, but because of the actions taken by both men after the fact. Dr. Frankenstein abandoned his creation, declaring it an abomination, never quite coming to terms with the facts. Faust on the other hand, had a genuine desire for knowledge, and while he may have misused his new found power on several occasions, he also accomplished a world of good.
