I simply do not understand “chemical castration” in cases like this.
It should be full, physical castration.
Just kill them.
Castration at the neck.
Right. Spread eagle naked in the town square and put peanut butter on their parts and set loose wild hogs.
Forget the “chemical” part.
Sharpen the knives.
I suppose “chemical castration” could be taken to mean submerging the appropriate body parts in fuming nitric acid, or some equally corrosive liquid. If so, I’d be in favor of it in this case.
