I side with Seuss in this, well at least from an ethical standpoint.

Taking cognitive steps toward revenge is to be unnecessarily hostile. Two wrongs sure don't make a right, and contemplating the validity of vengeance is a fallacy I think.

I've never been a vindictive sort, so I can't imagine what physiological changes I might feel in such a dilemma. If one commits a crime of passion in response to an ill act, that isn't vengeance, like Endlessness said it's an automation.

I'm convinced that revenge and vengeance are virulent emotions not necessarily synonymous with justice. In other words, I'm definitely not immune to such feelings, but I would never consider them to be virtuous.

I believe in rehabilitation over punishment, I suppose, if you actually believe in objective truth, I can see the integrity of your argument. I'm however agnostic to objective truth, it doesn't figure into my equations I'm afraid..
