Has anyone seen the movie Hidden with juliette Binoche? Who did it and why?

Question

When the credits came up it was sooooo annoying the way it ended without anyone knowing anything about who or why all the tapes were being sent.

Answer 1

Yes, I did see it. The person who sent the tapes was the man who was a young Algerian boy when his parents joined a protest in the 1960s and were killed, so the French family took care of him, but the young boy (the father) more or less framed the young Algerian boy, so his parents had him sent away. After that, when the Algerian boy grew up, he did not have a good life, and he resented the French boy for what he did. Surely, the Algerian was depressed and his last act was to commit suicide in front of the French man as to make him feel guilty for the rest of his life.
