That’s retribution, not justice. There is no payment or compensation for lives lost that makes people whole. Many problems can’t be fixed through punishment, and this is one of them. Instead ask “why” until you hit the root cause, and address that.

That's why punishment is required - both as a deterrant, and to inpart (to the people who suffered) a sense of justice being done.
