If people opted for perfection, then from Classical Aristotelian model's perspective - Western philosophy and Literature emerged mainly from his Poetics - people will never experience "the imitation of an Action". Action here doesn't mean action as in dictionary terms, but the Universal aspect of Human Imitation. If they do not experience this, then they would never experience 'Catharsis' - the core of Tragedy.
I think only Tragedies touch the verges of human reality. I have never viewed comedies that way. Albeit Merchant of Venice - Shakespearean dramas were never considered pure tragedies but Tragi-Comedies - despite being more along the lines of a Comedy, had many underlying racial messages. But I rather enjoyed the reality of Macbeth or Hamlet more. This is why the characters who display reality are valued, and reality lies in Hamartia and the general human flaws.
My two cents on this, as I cannot imagine or fathom anyone liking a bland character who offers no human side to him.
