You know, one can inflict trauma that won't be forgotten in 10+ years without any rape. Which wouldn't be a cause for even a fine, or a day behind bars, or lower social prestige of the person doing it.

While with rape - I'm all in support of killing attackers in self-defense, it's justified.

But if the crime is already done, and if you have them behind bars, and the facts are established, then every hour and every day their personality changes, and becomes further and further from the one that committed that crime.

And the purpose of the system in theory is not to punish or destroy. It's to redeem. You are nobody to attempt anything else.
