castrated offenders have reoffended using instruments to compensate for their impotence.
As long as their mind is evil, what you do to their body has no truly reliable effect. Unless, of course, you kill them like you're supposed to.
Castration kills the sexual desires. It works most of the time. I am all for the death penalty though.
Indeed.
What more proof is needed that we are a devolved society? We put convicted child molesters on the street when we should be executing them. We get what we deserve.
Castrated offenders don't need to use instruments, depending upon the type. First, chemically castrated offenders are treated with this process in order to lower their sexual drive, not their ability to perform (though that can also be a consequence). As for actual castration (the removal of the testes), if done after puberty it does not even effect the ability to achieve erection (in fact, Roman women used to have their slaves castrated as they found the slave was then able to "maintain" longer than a non-castrated man).
So your argument is not to the point. People aren't chemically or physically castrated in order to prevent them from being able to rape; they are castrated to reduce their urge to have sex...
