There's nothing wrong with a universe without life, just as there's nothing wrong with a world without life. Mars, for example, is without life (as far as we know). Does that mean there's something wrong with Mars? I don't think so, in the same way there's nothing "wrong" with the Sun because it doesn't support life. That said, Earth's biosphere is a unique system that has endured terrible degradation in the past; the fact that so-called "rational animals" would cause it, not even out of malice but sheer intellectual laziness and moral cowardice, seems to me to define a very clear test of our collective mettle as humans. Right now, we're failing, and accelerating the failure.
