Not a hard choice. The rat is cute and that is it’s entire worth to the world. The girl has more to offer, even if you don’t believe in an inherent or divinely given worth to humans.
It’s not all lab rats of course. There is testing on beagles and chimps and other mammals. But if it saves human lives, there is no argument.
You want passion and truth? Okay. Teller and I would personally kill EVERY chimp in the world, with our bare hands, to save ONE street junkie…with AIDS.
