Ah, that we should all live by the poet's creed. It's amazing how you can take some mediocre lyrics and add some well written and performed music and they don't sound half bad. Or you can take great lyrics and dress up some ordinary music and that doesn't sound half bad either. Well, Donne's words make for fine poetry and it expresses a fine and noble "general" sentiment with which most of us (myself included) concur.

However, if you shoot an intruder who is about to do you or your family harm, how does that diminish you? I'd say that enhances your life just a little, wouldn't you? Remember "Ding Dong, the Witch is Dead"? Which old witch? The Wicked Witch! Well, Ding Dong the Butcher of Baghdad is dead too!

If you define death as an absolute evil, then no one can argue with you, by your definition. But if your honest, you would have to admit that there are necessary evils.
