Is Helplessness a Factor in Tears?

Helplessness is a major part of whatever would be the ultimate, primary evolutionary explanation for them. Helplessness obviously doesn't explain every case of tears or at least it seems difficult to like. I think about some of the moments in movies that make me cry the most ar when a character who you didn't know if you could depend on comes through. It's hard to see how that really relates to helplessness. Maybe you could make a kind of very abstract argument has something to do with needing help from others. But obviously, looking into a tooth bucket is a different matteri guess you just have to roll at it at that point.
