Restitution applies for especially for things where there can be restitution - vandalism, theft, white collar crime. Where personal injury comes in, it's not such a relevant concept. Or rather, it can only be part of it.

If you do someone wrong, you owe it to them to make it up insofar as you can, at whatever cost to yourself. And if you won't do it of your own will, the community has a responsibility to make you. There's always talk about people owing a debt to society, but in the first place the debt is to the person harmed by you.

It's largely when the law loses sight of that that the anger builds up and the wish for vengeance. All too often the needs of the victim are completely ignored.
