There's nothing inherently wrong with that. It is a fact that violence often can be avoided. This doesn't absolve the criminals of their guilt but it does mean people can learn to recognize danger signs and avoid many instances of violence. When faced with warning signs that a situation is developing, a lot of people feel like something is a bit off but they proceed anyway because they think they're just being paranoid.

Punishing people after the fact does nearly nothing to help victims. It doesn't undo any trauma, it doesn't bring the dead back. Avoiding violence is always the best option if possible.
