Revenge or jealousy killings often involve whom?

Revenge or jealousy killings typically involve a history of emotional or relational conflict between the perpetrator and the victim. These types of homicides are often motivated by strong emotions, such as anger, betrayal, or possessiveness, which stem from previous interactions or relationships. When a perpetrator feels wronged, either through infidelity or perceived slights, it can lead to violent outcomes against someone with whom they have a significant personal history.

The nature of such crimes suggests that the perpetrator usually has a personal stake in the relationship, which heightens their emotional response and can drive them to commit violent acts. In contrast, the other options suggest scenarios where such strong personal motivations are absent, making it less likely for revenge or jealousy to be the primary motive.
