It belongs to law, which is used to align the goal of a society or a country, capital punishment is a specific law, used by many countries in the world
In a world all countries compete with each other, the abolishment of capital punishment is one of the high standards for all societies and countries, there is no right or wrong to a high standard, just someone archived it and created a high standard for all others
High standards are used for competition, it sounds cool:
We choose to go to the Moon. We choose to go to the Moon… We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win, and the others, too.
But the truth is just the Soviet Union will do it if you don’t, and if you want to win, you have to accept the challenge
There is a standard war on going every second in the world among all the countries
