Im in favor of sentencing them with castration, there have been many rape incidents here in the philippines and its sad to say that some of the victims were children, and its not enough of a punishment to just put them behind bars, rapists wont learn until you punish them with a much greater sentence and i think castration is enough to shut them off their immoral acts.
Will castration prevent them in doing these acts? I mean will their desire or pleasure with sex will also be gone. If that so, then maybe castration would be better. Sometimes, not only their desire for sex drives them to rape but also some are under influenced of alcohol and illegal drugs. Maybe these rapists should be killed. Castration could be used as punishment but I am waiting for the death penalty to imposed.
