Committing a crime and getting away with it is worse for the criminal than for the victim.
The criminal commits a bad action, and remains unpunished by it, thus becoming a bad person and staining their soul. The victim has no choice in his suffering, but his soul remains free from the evil that plagues the criminal.
To go even further, that criminal, if given the choice to run away or turn himself in, should always choose to turn himself in for his own benefit, since punishment, being a good thing, makes him a better person.
