Did North Korea ever had legal slavery, massacred it's indigenous population or used weapons of mass destruction on foreign cities?
And comparing Singapore to North Korea is just absurd. You might as well just reference the Nazi's and be done with Godwin's law (http://en.wikipedia.org/wiki/Godwin's_law)
Take a look at the Roman Empire which, despite everything, made the lot of ordinary people better.
North Korea probably meets my definition of evil, but I really don't know enough. Nazi Germany, Stalin and his apparatus. Pol Pot.
Edit: among millions worldwide, I marched in protest against the massacre at Tien an men square. My mother, who has far better cred in this area than I do (having been imprisoned and tortured as a political prisoner) argued in favor of the Chinese government — she said China wasn't ready for democracy and far more people would suffer in a chaotic transition than if the government were allowed to reform at its own pace. It's imponderabe — we can only try to do what we think is right.
Plus Tloewald's post was satire, pointing out that many countries that are not considered evil (namely USA - in his example) have committed far worse atrocities under their government than Singapore ever has has. Thus it's a bit of a stretch to call Singapore's government evil over this news item. Tloewald's point wasn't meant to be taken as a literal checklist for what constitutes as an "evil government".
