Kindness
Voluntary action to reduce another's actual harm or to help them toward what they would choose if able -- without crossing their boundaries or overriding the consent of a capable agent. Kindness is offered, not owed; it cannot be demanded, enforced, or taken. What is forced on someone is not kindness but harm, whatever name is given to it.
For a capable agent, kindness respects refusal: help only with permission, or in ways that do not trespass on body, property, or agreements. For someone who temporarily lacks the capacity to understand a real risk -- such as a young child or a temporarily incapacitated person -- kindness may include the minimum necessary temporary guardianship to prevent harms they cannot yet evaluate, always aimed at restoring full self-ownership as soon as they are able. Guardianship that exceeds what is needed, lasts without end, or keeps capacity from growing is not kindness but control.
Kindness is not reciprocity, justice, or love: it does not erase guilt, close moral debt, or require an ongoing bond. It is good when it respects consent and creates no unwilling victim; it is not good when it overrides autonomy, hides deception, or treats capable adults as if they were unable to choose.
