Mbh 12.95.4b

Even he that is wicked should be subdued by fair means. It is better to lay down life itself in the observance of righteousness than to win victory by sinful means. Like a cow, O king, perpetrated sin does not immediately produce its fruits. That sin overwhelms the perpetrator after consuming his roots and branches. A sinful person, acquiring wealth by sinful means, rejoices greatly. But the sinner, gaining advancement by sinful ways, becomes wedded to sin. Thinking that virtue has no efficacy, he jeers at men of righteous behaviour. Disbelieving in virtue, he at last meets with destruction. Though enmeshed in the noose of Varuna, he still regards himself immortal. Like unto a large leathern bag puffed up with wind, the sinner dissociates himself entirely from virtue. Soon, however, he disappears like a tree on the riverside washed away with its very roots. Then people, beholding him resemble an earthen pot broken on a stony surface, speak of him as he deserves. The king should, therefore, seek both victory and the enhancement of his resources, by righteous means."'"
