Just because you are searching on odd things does not make you want to commit them, maybe you are researching for a book.
You would want the book to be realistic as possible.
Maybe someone is acting supicious and you think you might be slowly poisoned or something like that. You would definately want to look up why and how someone is doing this.
There are many reasons to search information on the web and it is not always to harm/hurt or even idle curiosity.
