How bad is the Dark Web?

"I mean, how bad could it be?" Is literally what my friend said to my face. They are in dark web now, talking with strangers. It was so weird. I mean, like I showed her multiple videos, showing her how bad it is and there they were downloading songs and music from pirate bay and talking with strangers in "talk with john doe". I mean like, what the fuck! 5 days back, she texted me saying she talked with a pedophile for 2 hrs straight!! What is wrong with people nowadays?!
