Not trying to be rude but that’s what most animals which is pretty much what demons are compared too, predators that target humans, do on a daily. Even early humans. The point biologically is to keep your species going so even if it shows empathy it doesn’t really prove anything because that’s a pretty normal response
Not really. Animals of the same species fight more than they cooperate with cooperation often being attributed to evolution not them thinking about it and coming to a conclusion, and keeping a species going is more the work of evolutionary traits than them doing something for the greater good, a concept which is inconceivable to the average animal.
