Will preface my remarks by saying that, halfway through my last year, a bloke I went to school with died of a heroin overdose. He'd already dropped out by that stage and everyone knew what was going on, but when I saw him two days before the end it came as a complete shock. He was a walking corpse. Yes, heroin dealers are the scum of the earth.
However.
Let's leave aside any conjecture about Nguyen's motives in this case. He committed a serious offence and deserves to be punished by the law -- by spending an awfully long time in jail. It is indisputable that Nguyen's actions had the potential to cause the deaths of many people. But how anyone's interests are served by the deliberate taking of a human life, the conduct of a killing in the name of vengeance, is unfathomable.
Anyone in any doubt over this should read George Orwell's 1931 essay, 'A Hanging' (in which we never learn the offence the condemned man committed). In its course, the hanging party are walking to the gallows:
"This man was not dying, he was alive just as we were alive. All the organs of his body were working -- bowels digesting food, skin renewing itself, nails growing, tissues forming -- all toiling away in solemn foolery."
This is the crux of the issue. The state is intervening and taking from Nguyen all he has left -- his life. "That which is most precious to him," to borrow from Camus. Death comes as an inevitability, via an accident, through bad luck or as the consequence of poor judgement. But let's not beat about the bush: to kill an otherwise healthy, functioning human being amounts to murder and nothing else.
Some will take a religious angle to the argument, and will say that the condemned prisoner will be judged before God. This ignores the fact that they will be judged before God and their conscience, in their own mind, throughout the course of a lengthy imprisonment. And there is a profound difference between forcing someone to spend the vast majority of their life, perhaps its entire remainder, without freedom, and extinguishing it by deliberate action.
Take a hypothetical case where arguments over the levels of greed, or foolishness, or any other motive you care to name, are redundant because of the heinous nature of the crime. The murder of a child, say. The offender embodies evil in its most shocking and confronting form. By sentencing them to life in prison, perhaps we inflict on them fifty years of the constant torment of remorse. If so, good. If not, and they remain unrepentant, at least we can say this: that although you committed a crime against all of us as a society, we did not for a moment consider emulating your actions. This should let you know what we think of you, and we will let you know it for as long as you live.
I urge everyone to read 'A Hanging'. It draws awareness to the brutal nonchalance with which the state can destroy a human life. We are all alive and sometimes need to be reminded of the fact. Whatever your religious belief, for the moment at least it is the one thing you have that no-one should ever be able to take from you. No matter what you do, no matter how monstrous your actions, no matter how much the rest of us despise you. It is incontrovertibly yours.
It may be perfectly legal for Singapore to kill Nguyen Tuong Van, but is is morally wrong.
