> people will die.

I don't think that's a good thing. But if we DON'T do anything, then even more poeple are likely to suffer. So while people dying is not a good thing, a thousand people dying is better than a million people dying because we don't do anything.

Same thing about burning your hand. It's not a good thing to burn your hand, but burning your hand once when you're young probably saves you from a more serious accident later on.
