The "Rightness" of Heros

You either die a hero, or you live long enough to see yourself become the villain

Is a great line. There's a resonance to it. There's something to it that feels right and true. But why is that? Is that simply because, as watchers of heroism, we so recently end up with disappointment when the heros fall. Is it because such falls seem so commonplace that there's almost an inevitability to it?

And why is that it that such seeming inevitability has set it? Is it that, once you become a hero, you feel compelled to do more and more to achieve that heroic affirmation ...and that with each successive heroic act, that affirmation conveys a feeling of what was done was The Right Thing^TM? And is it similarly inevitable that, with being so frequently credited for doing The Right Thing^TM that you begin to assume that you, yourself, are inherently Right^TM. And being Right^TM, you reach a state of feeling above reproach? And, once you reach that state, you start doing things that you think are right, but are, really, only right in your mind?

I dunno. Don't really have answers - just questions that are probably very trite. It only really comes up because some neuron was provoked to fire in response to all of the turmoil surrounding various PDs ...especially of the NYPD. In any case, it feels like similar forces are at play.
