"Well, that sucked (that people are dead)?, but let us move on (like nothing has ever happened?)", is that the mindset you want the world to adopt?
We don't want to be careless with human lives, but it's also not helpful to play a finger-pointing blame game every time there's an accident.
It sure is helpful if it can prevent loss of human life in the future, even it slows down the "progress" a bit and some company loses some of its valuation and business...
