break one's promise

Show me a country where it was honourable to rob me of the fruit of my toil, to break one's promise, to lie in order to hurt, to calumniate, to assassinate, to poison, to be ungrateful towards a benefactor, to beat one's father and one's mother when they offer you food.

I promised I wouldn't; it would be dreadful to break one's promise.

But as I see it, it is, and must always be, something despicable to break one's promise, and it becomes unpardonable when a woman and her child are involved.
