TWO:But if penal laws thus express the wide variability of human morality, they also contribute to make actions moral or immoral according to the penalties by which they enforce or prevent them. For not[74] only does whatever is immoral tend to become penal, but anything can be made immoral by being first made penal; and hence indifferent actions often remain immoral long after they have ceased to be actually punishable. Thus the Jews made Sabbath-breaking equally immoral with homicide or adultery, by affixing to each of them the same capital penalty; and the former offence, though it no longer forms part of any criminal code, has still as much moral force against it as many an offence directly punishable by the law.The opponents of capital punishment may fairly, therefore, draw an argument in their favour from the fact that so many parts of the world have found it not incompatible with the general security of life to erase the death penalty from their list of deterrent agencies. It is better to rely on so plain a fact than on statistics which, like two-edged weapons, often cut both ways. The frequency of executions in one country and their total absence in another may severally coexist with great numerical equality in the number of murders committed in each. It is always better, therefore, to look for some other cause for a given number of murders than the kind of punishment directed to their repression. They may[45] depend on a thousand other things, which it is difficult to ascertain or eliminate. Thus both in Bavaria, where capital punishment has been retained, and in Switzerland, where it had been abolished in 1874, murders have increased greatly in recent years; and this fact has, with great probability, been attributed to the influence of bad habits contracted during the Franco-German war.
