A better example than you think. Remember how the first commandment is (paraphrased, lol, how disappointed my mother would be) "Thou shalt worship no other god before me" or something to that effect.
Hero worship is what weak-minded fans of celebrities do. There were celebrities back then too, just on a smaller scale, and the early builders of Judaism realized the power of the individual to sway someone.
So actually I like the example.

p.s. I think that if you look back into history, you can see many, many instances where religion has had a negative or constrictive effect on the society in which it is involved. But you have a hard time finding stories of faith or spirituality having a negative effect, as these are the true essences of the good human. Religion, as an earthly institution, is subject to the same corruptions and failings as any other human endeavour, and thus is worth keeping an eye on.
