IMO that is a matter of perspective.
Turn it around instead.
Malaria isnt beutifull, worms eating through a decaying corps isnt beautifull, a mudslide wiping out villages isnt beautifull, kids with distended bellies dying out of starvation isnt beautifull, a rapist raping and murdering 8 year old kids isnt beautifull, vultures feasting on a dead and rotting animal isnt pretty.
Maby a pretty sunset in a mountain region, northern lights a cold winter night or a mighty thunderstorm might seem perfect and beautifull, but it doesnt mean the earth as a whole is perfect and beautifull. Id say the earth is a very very far from perfect. If I can imagine a better place than a omnipotent god would easily be able to create a better place. So either he choose to fill the earth with horror or its just a random creation in a mindless universe...
In the end beauty is just a creation of the human mind. The universe cares not about beauty. Its more likely we have evolved to appriciate some of the things in our world.
Thats just my view offcourse
