If you want something "so terrible it was locked away", I suppose you mean something above snuff films/filmed murders. I expect that you know pretty much anything above that is illegal, so I wouldn't expect to simply come across it on the normal web.

If you want easy inspiration- take a look at your life, your world view, your own experiences, and anything that comes into your head after doing so. You'll find an idea or two.
