Thieves are not so bad, and killing wears all possible costumes. There is no death, no murder that is better than any other. If you can kill me, the manner hardly bears consideration. You want to kill your own father, and you think it will make your sleep easier for the next seventy years if you can say you did it honorably. But your honor is blackened by patricide, and no amount of high-sounding formalities will make it white again.
