What happens when you ignore justice in the city, according to Hesiod

But you, Perses, listen to right and do not foster violence; for violence is bad for a poor man. Even the prosperous cannot easily bear its burden, but is weighed down under it when he has fallen into delusion. The better path is to go by on the other side toward justice; for Justice beats Outrage when she comes at length to the end of the race. But only when he has suffered does the fool learn this. For Oath keeps pace with wrong judgments.

There is a noise when Justice is being dragged in the way where those who devour bribes and give sentence with crooked judgments, take her. And she, wrapped in mist, follows to the city and haunts of the people, weeping, and bringing mischief to men, even to such as have driven her forth in that they did not deal straightly with her.

But they who give straight judgments to strangers and to the men of the land, and go not aside from what is just, their city flourishes, and the people prosper in it: Peace, the nurse of children, is abroad in their land, and all-seeing Zeus never decrees cruel war against them. Neither famine nor disaster ever haunt men who do true justice; but light-heartedly they tend the fields which are all their care. The earth bears them victual in plenty, and on the mountains the oak bears acorns upon the top and bees in the midst. Their woolly sheep are laden with fleeces; their women bear children like their parents. They flourish continually with good things, and do not travel on ships, for the grain-giving earth bears them fruit.

But for those who practise violence and cruel deeds far-seeing Zeus, the son of Kronos, ordains a punishment. Often even a whole city suffers for a bad man who sins and devises presumptuous deeds, and the son of Kronos lays great troubles upon the people, famine and plague together, so that the men perish away, and their women do not bear children, and their houses become few, through the contriving of Olympian Zeus. And again, at another time, the son of Kronos either destroys their wide army, or their walls, or else makes an end of their ships on the sea
