This saying is a pet peeve of mine, because it’s so contrary to the actual meaning of “eye for an eye”, which is a prohibition against escalation. Like in this case the guy injured someone’s neck and wrist, so the maximum punishment would be injuring his neck and wrist, not killing him. That’s not to say “eye for an eye” is an ideal justice system, just that it is opposed to wanton revenge and violence.
It was in fact very badly written, with stuff like wage changes taking effect “immediately” (in practice 5 days after vote counts are certified).
