Only in certain fucked up moral systems. Though I guess Confucianism would be one of those:

>The Duke of She said to Confucius, “Among my people there is one we call ‘Upright Gong.’ When his father stole a sheep, he reported him to the authorities.”

>Confucius replied, “Among my people, those who we consider ‘upright’ are different from this: fathers cover up for their sons, and sons cover up for their fathers. ‘Uprightness’ is to be found in this.”

-from the Confucian Analects
