To Rowling, a diary is a very scary object. She said in an interview that "the temptation particularly for a young girl, [is] to pour out her heart to a diary." Rowling's little sister Diane was prone to this, and her great fear was that someone would read her diary. This gave Rowling the idea to have a diary that is, in itself, against the confider. When asked what would have happened if Ginny had died and Riddle had managed to escape, Rowling declined to give a straight answer, but revealed that "it would have strengthened the present-day Voldemort considerably."
