The Kural in life
Say it to the face, or not at all.
Valluvar draws a clear line about where criticism belongs. Even if someone has rebuked you to your face without any mercy, do not say behind their back a careless word that takes no thought of its consequences. Harsh truth spoken openly may be allowed; the same words whispered in a person's absence are not.
Parimelazhagar: the back-word ignores its harm.
Parimelazhagar contrasts two speeches: one said to the face, even without kindly restraint, is open and answerable; but the 'back-word' is one 'that does not look to the harm that follows.' The difference is accountability — the face-to-face word can be met and corrected; the absent-word does damage no one present can check. So refuse the latter even if provoked.
The integrity test of criticism.
Here is a workable rule for an age of group chats and whispered asides: would you say this with the person in the room? If yes, say it openly and own it. If not, the words have failed the test — not because criticism is wrong, but because criticism that hides from its target is the cowardly, consequence-blind kind Valluvar forbids. Provocation does not lift the rule; even a face-full of insults does not license a behind-the-back reply.
Don't say behind a back what you wouldn't (or didn't) say to the face.

Use the test: would you say it with the person in the room?
For an age of group chats and whispered asides, use Valluvar's rule: would you say this with the person present? If yes, say it openly and own it. If not, the words fail the test — criticism that hides from its target is the cowardly kind. And note: even being insulted to your face doesn't license a behind-the-back reply.
