I have two issues with this - 1)' Treatment' - which means that once stopped, the recipient gains his lost glory and b) 'Reduces' - Means not zero. So there's still some lust leftover.
The intention of castration is to penalize monsters who have taken advantage of minors and babies - and fully deserve a punishment that renders them incapable of ever trying to do anything so horrendous.
I think the contention by human rights groups is that if capital punishment can be made more humane (injections instead of electric shocks), then why not apply the same analogy to castration?
But since the intention of capital punishment is 'removal' and not 'restraint', then by the same measure, we should stick to the good old method of castration.
