He was acting on a reason other than the avoidance of pain. The sentiment was loyalty, and it felt glorious.
We have absolutely abandoned any idea of nationalist loyalty. We are deliberately putting a world order before our loyalty to our own country.
Beloved-of-the-Gods, King Piyadasi, conquered the Kalingas eight years after his coronation. One hundred and fifty thousand were deported, one hundred thousand were killed and many more died (from other causes). After the Kalingas had been conquered, Beloved-of-the-Gods came to feel a strong inclination towards the Dhamma, a love for the Dhamma and for instruction in Dhamma. Now Beloved-of-the-Gods feels deep remorse for having conquered the Kalingas. Indeed, Beloved-of-the-Gods is deeply pained by the killing, dying and deportation that take place when an unconquered country is conquered. But Beloved-of-the-Gods is pained even more by this that Brahmins, ascetics, and householders of different religions who live in those countries, and who are respectful to superiors, to mother and father, to elders, and who behave properly and have strong loyalty towards friends, acquaintances, companions, relatives, servants and employees that they are injured, killed or separated from their loved ones. Even those who are not affected (by all this) suffer when they see friends, acquaintances, companions and relatives affected. These misfortunes befall all (as a result of war), and this pains Beloved-of-the-Gods. There is no country, except among the Greeks, where these two groups, Brahmins and ascetics, are not found, and there is no country where people are not devoted to one or another religion. Therefore the killing, death or deportation of a hundredth, or even a thousandth part of those who died during the conquest of Kalinga now pains Beloved-of-the-Gods. Now Beloved-of-the-Gods thinks that even those who do wrong should be forgiven where forgiveness is possible.
The general election of 1983 has produced one important result that has passed virtually without comment in the media. It is that, for the first time since 1945, a political party with an openly socialist policy has received the support of over eight and a half million people. This is a remarkable development by any standards and it deserves some analysis ... the 1983 Labour manifesto commanded the loyalty of millions of voters and a democratic socialist bridge-head in public understanding and support can be made.
