Meaning
To cause someone present pain for their eventual benefit - harsh treatment serving, in the actor's mind at least, a benevolent purpose. Usually said to justify unwelcome medicine: blunt feedback, strict discipline, a relationship ended supposedly for the other person's sake. Conversational in register and often rueful, sometimes self-serving, since the claimed kindness can be partly self-excuse. The paradox is Shakespeare's own and the sense has not shifted since he wrote it. Conversational; typically justifies harshness, sometimes with a self-aware or self-excusing edge. Regional use: General English (Shakespearean origin).
Origin
Hamlet, Act 3 Scene 4 (c. 1600), the closet scene. After stabbing Polonius through the arras, Hamlet confronts Gertrude over her hasty marriage to Claudius and justifies his harsh words with 'I must be cruel only to be kind. This bad begins, and worse remains behind' (Folger text; many other modern editions print 'I must be cruel, only to be kind: Thus bad begins'). No Sweat Shakespeare lists it among the idioms derived directly from this line, and no earlier fixed use is cited. The shortened everyday form shed 'only' on its way into general speech, and the paradox echoes widely in later culture, most famously in Nick Lowe's 1979 hit song 'Cruel to Be Kind'.
