These people care about helping those people close to them - their “in-group.”
Benevolent people are motivated to enhance the wellbeing of those close to them. The closer the relationship, the higher the drive to help that person. That’s not to say that benevolent people will not help a stranger. Quite the opposite. Rather that their drive to help people is most activated towards individuals (vs. broad groups) and the strength of that drive is correlated with the closeness of the relationship.
Benevolence is different from Universalism primarily in its target group. While benevolent people channel their concern for others to those close to them, universalists have a more broad concern for humanity and nature as a whole.
The benevolent lover, similar to the altruistic lover, will have a strong drive to support their partner. Their love expression may manifest in emotional support or acts of service. They will be the first to give a helpful hand and will go out of their way to devote time and energy to help their partner when they are in need.
