Even where people in different cultures agree they may all have gone wrong.

What we need is legislation, not negotiation, for the entire globe.

I have been brought up in a culture where capital punishment is indeed anathema. I have always thought of myself as a principled opponent to capital punishment. However, when thinking about how the topic is handled in other cultures, in particular the American, Russian and Chinese ones, I have realised that my own tack on the issue was utterly superficial.

I want to think that there are better ways of obviating murder than to resort to capital punishment, but I realise that this may be wishful thinking on my part.

The US two party system is very different, of course. Here the people decides about who should rule them, but it is not reasonable to claim that the people rules itself through the political institutions. In comparison, I find that the standard European system is better, also as a model for global democracy.

In many European countries we have populist indirect democratic systems. The people elect, in a proportionate manner, a parliament. The parliament with all its parties is representative of the political opinions among the citizens. It is reasonable to claim that the people rule itself through the political institutions.

I have now come to the conclusion (roughly) that capital punishment is defensible, if it can be shown to have a deterrent effect on murder. In that case, a few executions save not only some people from being murdered but also some people from becoming murders.
