Ah, OK that does now make sense to me, thanks. I think I didn't manage to see that meaning because the comment it was replying to had nothing to do with humans

Ah, OK that does now make sense to me, thanks. I think I didn't manage to see that meaning because the comment it was replying to had nothing to do with humans thinking orcas want to eat them, it was about orcas bringing food (like dead fish) to give to the humans. So more like a pet cat bringing a dead mouse to its owner than a cat in the garden fearing that the human wants to eat it?
