How could something exist? How could morality exist? How could free will exist?
Morality implies absolute judgement. It's impossible.
Free will implies... well, I can't even imagine how free will could be possible.
If there was something, what would it be?
What "exists" (maybe) is some kind of automatic, irrational, completely meaningless and impersonal happening. No one is in charge of anything, because there is no one. There's just happening without something happening. Absurd verbs without nouns.
Is this nihilism? Maybe. But nihilism does not necessarily imply darkness. It can be neutral.
