Kind of depends on whether there is a God. If there is a God and they intended for certain things to be the way they are, then it's something out of a horror story in places. If it's all chance then, there isn't mallice there. It's just that we've happened to develop a sense of right and wrong- or rather, it's been ingrained in us and it upsets us when things are cruel and unfair.
But, I think it has both. Some phenomenally beautiful things- both natural and manmade and some very unpleasant things- both natural and manmade.
From my own perspective, I've known people who I've believed to love and appreciate life or, at least like it and, I can see it from their perspective. From my own perspective, it just doesn't feel worth the effort to sustain. Plus, it carries so many things to feel sad, afraid and worried about. I'm an antinatilist not because I believe all lives turn out badly but because there are so many huge risks in this world that can badly impact them and there's nothing we can do to properly mitigate those risks.
