I think that what makes TAS good is how, at least in characters’ first appearances, it seems that the idea is precisely to show how social problems have driven these “villains” crazy, and the objective is always, with some exceptions (i.e. Red Claw), to make the audience sympathize with them, producing social awareness of this problems in the audience. Unfortunately, as the characters are reused, they are reduced to caricatured villains and the incentive to sympathize with them fades. For example, Two-Face appears as an antagonist in 6 episodes and only in the stories “Two-Face” and “Second Chance” is he treated as a human being. And this only gets worse in the sequel in The New Batman Adventures. I actually think it’s a good thing that, despite generally showing some sympathy, Batman always opposes his antagonists when they reach a point of social rupture: Batman is not a revolutionary, because Bruce Wayne could never be a revolutionary. Batman not being exactly on the side I would be on is not a problem: it gives the cartoon a verisimilitude.

Now, regarding “the hero we need” and other ideas of the sort, present in Nolan’s films and Miller’s comics, they are radically fascist, there’s nothing to discuss.
