An interesting thought exercise - aimed at those who claim to be more truthful than all the other liars.
3 newborn babies lifes are at risk, to save them you have to be interviewed on the local news station where you must lie to the 3million views
do you LIE to 3m people? to save 3 lives?
If you think this lie is OK... then before you call other people liars, you might want to first seek there context and motivations...
