Should Diaries Be Published or Not?

I understand that diaries are very personal and powerful; they are literally the lives of other people. On one hand, they should not be shared because they can hurt the people that are discussed and mentioned in them.  They can also distort the view of the writer to the audience.  This was stated in one of entries by Virginia Woolf when the author wrote that she only writes in her diaries when she is in certain moods.  This allows a reader to understand just a small part of someone and not be able fully grasp who they are.  On the contrary, sharing a journal or diary shares historical evidence and helps people to learn.  For example, by using Virginia Woolf's diaries, writers could experiment with more styles for their writing.  One compromise between these two sides could be that a certain amount of time like one hundred years after the author's death be required (unless the author specifies otherwise) before the diaries are published.  With this idea, the people who are involved in the diaries are no longer there to be effected by them and people can still learn from them.
