Ghosts and The Big Q

Mrs. Alving chose not to tell her son about the awful things her father did because she believed she was protecting him, but did she make the right choice? There are arguments for both sides of this question, but I believe that in the end she made the right choice. Although Osvald never really knew his "true" father his life is probably better for not knowing him. If he had known how his father behaved, he might have chosen to believe that what his father did was okay.
