What defines a perfect human?

My friend and I were talking the other day about how for a perfect society to exist, surely every person within that society must also be perfect, which lead us to discussing what defines a perfect human.

Clearly we live in a imperfect world and therefore it can never be accomplished, but we realised there are multiple ways in which a perfect human could be defined. This included such parameters such as emotional stability, morally perfect, physically perfect (whether or not this is even possible) and a whole array of other parameters that have escaped my memory.

What do you think defines the perfect human, assuming it's even possible in the first place? Should it just be defined by one parameter or a mix, and would some parameters be valued higher over others? For example, is a perfect moral compass more valued over physical perfection? I would love to hear your guys take on the question.

EDIT: By perfect I mean functioning within a society perfectly.
