Been there. The Deepwebs is literally like 20 websites. Its talked about to scare redditfags into wetting their beds more than usual.
And yeah, there's mentions and talk of illegal things, like hitmen, child porn, murder, etc. Almost all of it is just people talking about it, and stuff around it that they've supposedly done. And all that is accessible there, on Deepwebs, live suicides, child porn, etc, is just as available on the regular internet if you know how to look for it.
In other words, its boring. You're ignorant. Humans are gross and disturbing and we all can't deny that we aren't fascinated enough by things like real gore to just look away when its offered to us. that's human nature as well. The Deepwebbers, or simply a lot of people with a lot of time to spend on the internet, just accept that fact and look anyway because they can.
If this is all it takes for you to get "disturbed at how low the human race could have gotten" you should try watching the news some time. Have fun in the real world, bro.
