I mean Singapore has draconian punishments for crimes too but they correspondingly have next to no drug use. We lose tens of thousands of people to fentanyl every year, whole towns are devastated etc. Hanging a few drug smugglers is definitely the lesser evil.
That being said, I enjoy my individual rights in the US and wouldn’t live anywhere else but there is a valid argument to be made that our ethics are sometimes a little too short sighted/individualistic and not holistic enough.
(I’m also definitely against the death penalty, just trying to make a point)
