if u think he has no chance of being rehabilitated and could be a repeat offender after all the caning and squatting in jail cell, THEN just give him life imprisonment will do, no need to execute him what. I know executing him might save $ for the taxpayer lah, if $ is all u r concerned about then just say so. Don't try to take the moral high ground.

But if you wanna talk about moral principles, i think he also dun deserve to be executed. Only case where some1 might deserve to die is if he is a cold blooded murderer or terrorist bomber. U might be justified in taking revenge by forfeiting his life in dat case, if it is not against your spiritual beliefs and you are okay with the inhumane punishment of dealth penalty and you are sure you arrested the correct guilty terrorist because death is an irreversible punishment.

you also cannot compare the rehabilitation of this 'repeat sex offender' and a '1st time drug trafficker'. Nyugen is a 25yr old, no previous criminal record, shown true remorse, has vouched to turn over a new leaf. Prime candidate for rehabilitation. Will become useful for society again. He did it for greed and stupidity and now he realises his mistake. Why hang a man when he is down? Singapore society can learn to be more forgiving and compassionate. That will be progress for our nation.
