That only helps in punishing the wrongdoer. If you can avoid being a victim in the first place, yes, the wrongdoer will get away with doing something wrong (though much less wrong than if you succeeded in becoming a victim; e.g., he's guilty of running a red light rather than running a red light and causing a crash that resulted in someone's death), but the price you pay for making the wrongdoer guilty of a greater crime (homicide) is your life. Is that really worth it?

The whole right vs. wrong thing is only useful in assigning blame when something really bad happens, and society wants to punish someone to achieve "justice". But having justice isn't really useful if you're dead, and not really worth it IMO if you're maimed for life. It's better to avoid the whole incident in the first place. "Justice" is nothing more than a concept society created to prevent people from seeking personal vengeance.
