In non-Muslim nations, Muslims who rape should automatically face castration. Unlike in the West, where rapists have an individual motivation, Muslims have a religious/secular/political motivation to rape.
This being said, while a normal punishment for rape is imprisonment, if the rape goes beyond individual motivation, then it should be punished with the idea of deterrence.
In Sharia law, thieves can have their hand cut off, but women are seen as less than animals or even things, and are blamed if they are raped. So Muslim men need to be taught that women are not worthless, that they are valued.
And if they rape a woman, they will be castrated. Physically, not chemically.
Why stop at Muslims? Rape for “individual motivation” has the same traumatic effects on the victim.
Rapists of all creeds and colors need to be “fixed” in the same way that a male dog is “fixed”, except without the anesthesia. After being convicted in a fair trial, of course.
