"You might say that the moment when Lorenzino killed Alessandro was the most auspicious for a deed of that kind. The Medici had only recently been restored; Alessandro was the first ruler in Florence, who had worn a title; no more reckless, brutal, and insolent tyrant ever lived, and his right, even such as the Medici might have, to play the despot was involved in the doubt of his origin; the heroism of the great siege ought still to have survived in the people who withstood the forces of the whole German Empire for fifteen months; it seems as if the taking off of that single wretch should have ended the whole Medicean domination; but there was not a voice raised to second the homicide's appeal to the old love of liberty in Florence. The Medici party were able to impose a boy of eighteen upon the most fiery democracy that ever existed, and to hunt down and destroy Alessandro's murderer at their leisure. No," added the old man thoughtfully, "I think that the friends of progress must abandon assassination as invariably useless. The trouble was not that Alessandro was alive, but that Florence was dead. Assassination always comes too early or too late in any popular movement. It may be," said Mr. Waters, with a carefulness to do justice to assassination which made Colville smile, "that the modern scientific spirits may be able to evolve something useful from the principle, but considering the enormous abuses and perversions to which it is liable, I am very doubtful of it--very doubtful." Colville laughed. "I like your way of bringing a fresh mind to all these questions in history and morals, whether they are conventionally settled or not. Don't you think the modern scientific spirit could evolve something useful out of the old classic idea of suicide?" "Perhaps," said Mr. Waters; "I haven't yet thought it over. The worst thing about suicide--and this must always rank it below political assassination--is that its interest is purely personal. No man ever kills himself for the good of others." "That's certainly against it. We oughtn't to countenance such an abominably selfish practice. But you can't bring that charge against euthanasy. What have you to say of that?" "I have heard one of the most benevolent and tender-hearted men I ever knew defend it in cases of hopeless suffering. But I don't know that I should be prepared to take his ground. There appears to be something so sacred about human life that we must respect it even in spite of the prayers of the sufferer who asks us to end his irremediable misery." "Well," said Colville, "I suspect we must at least class murder with the ballet as a means of good. One might say there was still some virtue in the primal, eldest curse against bloodshed." "Oh, I don't by any means deny those things," said the old man, with the air of wishing to be scrupulously just. "Which way are you walking?"
