They're animals. Pure and simple. Rabid, frothing at the mouth, animals. They dishonor their heritage, their religion, and their nation. This foul act begs for revenge.
I hope we don't do it. Justice, absolutely. Revenge -- I don't think so. My gut says yes, smash them, smash them all, they, in fact, the whole region, responds to strength, not mercy. My brain says 'The cycle has to stop somewhere.'
Want to bet they didn't have this discussion?
