I believe that the best answer to this question would be a tragedy. However, there may be more than one genre that accomplishes this goal. A tragedy is, specifically, a form of drama. It, "treats in a serious and dignified style the sorrowful or terrible events encountered or caused by a heroic individual" (this is the definition given in Encyclopedia Britannica.) A tragedy most definitely depicts the flaws in human nature.
