> Yes, it is. People make mistakes. People have infinite possibility to grow, change and contribute to society. Snuffing everything someone is out because of an arbitrary society rule that ultimately does less harm than murder is indefensible.
Putting aside statistics on actual reform instead of fantastical infinite possibility, as I understand this policy mostly serves to deter foreigners from attempting the potentially very lucrative business of smuggling drugs into Singapore. Even if Singapore didn't take the "barbaric" approach of executing them, they would have to either host them as prisoners on their already very limited land, or go through the process of deporting them to their home country, where they might not even face any consequences and just try again. Why should they bear this burden for people who have no ties to Singapore and will never contribute anything to it?
