It’s actually sick, they already get a light sentence and also getting protected by the justice system while the victim they violated is heavily traumatized, probably for life. And what’s crazier is it’s happening more, I’m seeing it daily now every time I scroll, there’s another case. Something needs to be done
So, you’re basically asking why we have a judicial system.
If you look at world history pretty much every human society comes up with a code of what is okay and what isn’t, and once they get to a certain size they start standardizing punishments as well.
The reason for this is because it works a lot better than ad hoc justice which is too reliant on variables like who was there that day.
Not to mention emotions. Which is inherently biased.
