What is the origin of the idiom "kill someone with kindness" and when to use it?

The origin of the idiom "kill someone with kindness" is not precisely documented, but it likely stems from the idea that excessive kindness or niceness, when insincere or used as a form of manipulation or passive aggression, can have an overwhelming or negative effect on a person. It may be traced back to observations of human behavior and interactions, where individuals may employ excessive kindness as a way to irritate, confuse, or disarm someone with whom they have a disagreement or conflict. It is used when someone aims to diffuse tension, resolve conflicts, or address stubbornness or hostility through an overwhelming display of niceness.
