Au contraire. Getting them gelded would have salutary effect.
So sinning against the physical integrity of the human person is a good thing? You forget that Origen was a heretic who denied the divinity of Christ. I do not follow heretics into error, certainly one as ludacris as to mutilate healthy flesh. It is not the man's penis that causes him to sin. It is his weak will. Removing the penis and leaving the will intact is hardly a solution. You forget your place when you suggest such things.
