So because you don't understand which feelings this almost blind ugly little meatbag in that photo represents, there will be those who do and who will share the joy, making the world a little less depressing as fuck. Which is a benefit. But of course,. because you can't understand that, no one possibly can.
A friend of mine has a baby and he's certainly in that joy category. I guess it shouldn't surprise me because it was essential for the survival of the species, but I'm still surprised that people like babies. Kids can be cute when they're old enough to talk and use the toilet, and even then they're only cute if they're the charming kids-say-the-darnest-things sort and not the tantrum-throwing sort. Meanwhile puppies and kittens are cute from the moment they're born.
(Why do humans babies make such horrible sounds when they need something? A puppy whimpering makes me want to give it whatever it's asking for. A baby crying makes me angry. I suppose the crying is harder to simply ignore.)
