Care to elaborate? I was implying it should apply to other crime as well. In my perfect world, prison sentences would be a lot less common. Fairness is a fundamental compnent of justice. If there is a victim then the aggressor needs to be harmed in a similar way. Theft? Something if equal value should be taken from you. I also agree with "lashing" and damaging a persons body for certain crimes like rape for example (chemical or otherwise castration in addition to some torment).
Fines are a joke, a slap in the face of justice. The affect the poor only even when proportional to income. 25% of a poor person's wealth has much more impact than 25% of a billionaire's wealth or a corporation's profits.
While I believe in mercy strongly (especially when the victim supports it), justice has to have fairness and equal application and is better left not administered than administered partially.
