in such an area, is the irrelevance of the announcement to the rate of murders alleged, which had grown steadily while executions were carried out and was not accelerated by the halt in hangings. The results of my analysis, for what they are worth, may be added to the cogent and stronger reasons which Chaskalson P has supplied in paragraphs [119] and [120] for rejecting the contention addressed to us that the moratorium had contributed materially to the increase.
[183]Without empirical proof of the extent to which capital punishment worked as a deterrent, neither side could present any argument on the point better than the appeal to common sense that tends to be lodged whenever the debate is conducted. That the extreme penalty must inevitably be more terrifying than anything else was said, on the one hand, to speak for itself. It spoke superficially, we were told on the other, and unrealistically too. What stood to reason was this instead. A very large proportion of murderers were in no mood or state of mind at the time to contemplate or care about the consequences of their killings which they might personally suffer. Those rational enough to take account of them gambled by and large on their escape from detection and arrest, where the odds in their favour were often rather high. The prospect of conviction and punishment was much less immediate and seldom entered their thinking. It was fanciful, should that happen on relatively rare occasions, to imagine their being daunted by the possibility of a journey to the gallows, a journey taken by only a small percentage of convicted murderers even at the height of executions in this country, but not by the probability of incarceration in a jail for many years and perhaps for the rest of their lives. The second school of thought is the one which gets to grips with the realities of the matter, in my opinion, appraising them with a lot more plausibility and persuasiveness than any that attaches to the stark proposition of the first school.
[184]It is unnecessary, however, to go so far. The protagonists of capital punishment bear the burden of satisfying us that it is permissible under section 33(1). To the extent that their case depends upon the uniquely deterrent effect attributed to it, they must therefore convince us that it indeed serves such a purpose. Nothing less is expected from them in any event when human lives are at stake, lives which may not continue to be destroyed on the mere possibility that some good will come of it. In that task they have failed and, as far as one can see, could never have succeeded.
[185]In his judgment Chaskalson P has discussed retribution as another goal of punishment, and the arbitrariness and inequality contaminating our processes that culminate in executions. His treatment of the first subject will be found in paragraphs [129] to [131] and of the second one in paragraphs [48] to [54]. I share the view taken by him that retribution smacks too much of vengeance to be accepted, either on its own or in combination with other aims, as a worthy purpose of punishment in the enlightened society to which we South Africans have now committed ourselves, and that the expression of moral outrage which is its further and more defensible object can be communicated effectively by severe sentences of imprisonment. The inequality of which he has written may be curable in the long run, once it is not the result of the arbitrariness described by him. The same does not go, however, for the arbitrariness itself, a flaw in the edifice which Ackermann J has examined as well in paragraphs [158] to [165]. The problem of that is quite as intractable here as it has proved to be in the United States of America, where the courts
