The internet does neither bad nor good.
The internet is an amazing resource when you need certain information. Whether you need to know how to fix your PC, remove an ingrown toenail, bake a cake or construct a shotgun from basic parts in your garage... the internet provides the information.
If you use a search engine, such as Google, it will not throw "bad" things at you. It will not throw "good" things at you. Type in what you want and you'll find it. If you want "bad" things then you're going to find "bad" things. We are our own worst enemy in that regard.
Like I said, the internet is a resource. It is a tool to be used. The old saying still stands true: "Guns don't kill people, people kill people," and the same phrase can be applied to the internet.
