Jules Verne was the apple of my eye as a youth. I loved Captain Nemo the most. A renegade who abhorred war and the violence it had brought upon his loved ones. Although a man with a higher purpose, he became overwraught with his desire to stop violence.
You just can't stop violence with violence. There's always going to be someone with a bigger gun, more soldiers, more murderers. It's the nature of the energy.
Ultimately, any hero worthy of his name has to realize that he can't change the world through overt means, but must instead change it from within the hearts of those about him.
And so it is that all dictators, or men of power and persuasion, must ultimately face their own shortfall...the belief that they are more powerful than life, when in fact, it's the opposite. Life is more powerful than man.
