Evidence is limited but orcas might also do that to great white sharks. The orcas seem to sometimes work together to exterminate sharks from an area in a way that goes beyond just hunting them for food.

I can see gene fitness benefit but mating opportunities, how? "hey, me and maman uh killed your baby, wanna pump out a replacement real quick?"
