For me a life that is screwed up is one where someone can happily wander down the aisles of a supermarket selecting meat that he or she knows nothing about - how the animal was raised and how it was killed. That's an abrogation of responsibility (the Pontius Pilate approach to shopping if you like). It's also a tacit collusion in intensive farming and cruelty on an unimaginable scale. When you buy 'cheap' meat, think of the real price.
If you are going to eat meat, you shoud be prepared to acquaint yourself with its origins and accept them morally. The animal deserves at least that dignity.
Oh, and Shambles - shot, any day!
