People are probably less bothered by it because it happened so long ago, and was not perpetrated by any kind of thinking agent. The process of evolution definitely entails a lot of suffering, though. Consider almost any attribute of modern day humans, fear of heights, say. Millions of creatures had to fall to their deaths (many of them very similar to modern humans) to etch that fear of heights into the surviving generations. Or take the gag reflex: many deaths by choking. The immune system: billions of deaths by disease and infection. It would certainly be immoral to inflict such things, if you had the ability to prevent them.
