Fatimah, I must respectful disagree, habibti! Blame can serve a useful purpose. That's how we learn from accidents and tragedy. Blame is why we use seat belts, flame retardant children's clothes, learn the Heimlich, and on and on. If we never learn we never improve. That's why we have investigations that assign blame in air accidents - pilot error, structural failure, maintenance issues, etc.
