I think a big aspect of ingrained behaviors like love is about shaping the behaviors of the evolved agents to ‘higher average utility behavior patterns’. For love of non-kin / non-mates, this is probably something like “this social organism will tend to do better when it chooses to remain in close social proximity to allies.” So it’s not just about gaining the trust and assistance of community members, it’s also about making sacrifices to stay near enough to them that they could help you if you found yourself in need. Community building is about finding ways of credibly signalling contracts of mutual support, and building histories of repeated incidences of mutual support. Adversity can bring a group closer together by giving them the chance to demonstrate supportive behaviors for each other, increasing the expectation that such will happen again in the future.
