Imagine a person distorting messages between relatives so that each becomes more hostile toward the other. This approaches the sense of خَبَّبَ: intentionally damaging a relationship. By contrast, hearing a truthful complaint about harm, assisting someone's safety, and facilitating appropriate support can be genuine goodwill.
Example 1: Deliberately spreading false rumors to turn spouses against one another is harmful interference.
Example 2: Helping a person facing mistreatment reach safe and trustworthy support is not malicious manipulation.
Purpose, method, and actual effects matter in making the distinction.
