There are probably some good things there...one turning point in my hope for humanity was reading a thread, just a text discussion that I came across on the Dark Net. Besides the fact that it involved kids, I won't say anything about it. But it horrifies me to this day when I think back to it.
Anonymity and freedom - I don't know if it's a good thing. Because then you see the worst of humanity, unedited. And that's really the worst thing that exists in the universe.
