From George Bernard Shaw, Preface to Major Barbara (1905-1907)

Undershaft, the hero of Major Barbara, is simply a man who, having grasped the fact that poverty is a crime, knows that when society offered him the alternative of poverty or a lucrative trade in death and destruction, it offered him, not a choice between opulent villainy and humble virtue, but between energetic enterprise and cowardly infamy. His conduct stands the Kantian test, which Peter Shirley's does not. Peter Shirley is what we call the honest poor man. Undershaft is what we call the wicked rich one: Shirley is Lazarus, Undershaft Dives. Well, the misery of the world is due to the fact that the great mass of men act and believe as Peter Shirley acts and believes. If they acted and believed as Undershaft acts and believes, the immediate result would be a revolution of incalculable beneficence. To be wealthy, says Undershaft, is with me a point of honor for which I am prepared to kill at the risk of my own life. This preparedness is, as he says, the final test of sincerity. Like Froissart's medieval hero, who saw that "to rob and pill was a good life," he is not the dupe of that public sentiment against killing which is propagated and endowed by people who would otherwise be killed themselves, or of the mouth-honor paid to poverty and obedience by rich and insubordinate do-nothings who want to rob the poor without courage and command them without superiority.

[...]

the deliberate infliction of malicious injuries which now goes on under the name of punishment [should] be abandoned; so that the thief, the ruffian, the gambler, and the beggar, may without inhumanity be handed over to the law, and made to understand that a State which is too humane to punish will also be too thrifty to waste the life of honest men in watching or restraining dishonest ones. That is why we do not imprison dogs. We even take our chance of their first bite. But if a dog delights to bark and bite, it goes to the lethal chamber. That seems to me sensible. To allow the dog to expiate his bite by a period of torment, and then let him loose in a much more savage condition (for the chain makes a dog savage) to bite again and expiate again, having meanwhile spent a great deal of human life and happiness in the task of chaining and feeding and tormenting him, seems to me idiotic and superstitious. Yet that is what we do to men who bark and bite and steal. It would be far more sensible to put up with their vices, as we put up with their illnesses, until they give more trouble than they are worth, at which point we should, with many apologies and expressions of sympathy, and some generosity in complying with their last wishes, then, place them in the lethal chamber and get rid of them. Under no circumstances should they be allowed to expiate their misdeeds by a manufactured penalty, to subscribe to a charity, or to compensate the victims. If there is to be no punishment there can be no forgiveness. We shall never have real moral responsibility until everyone knows that his deeds are irrevocable, and that his life depends on his usefulness. Hitherto, alas! humanity has never dared face these hard facts.
