Roberto Bolaño said this quote
“ The heart of the matter is whether knowing evil (or sin or crime or whatever you want to call it) is random or purposeful. If it's purposeful, we can fight it, it's hard to defeat, but we have a chance, like two boxers in the same weight class, more or less. If it's random, on the other hand, we're fucked, and we'll just have to hope that God, if He exists, has mercy on us. And that's what it all comes down to. ”
