The question of "which Korea is the bad one" is an oversimplification. North Korea (officially the Democratic People's Republic of Korea) is often considered the "bad" one due to its authoritarian regime with severe human rights violations, extreme restrictions on freedoms, state-controlled media, political prison camps, and nuclear weapons ambitions. Its government operates as a dictatorship under the Kim family with a centrally planned economy and isolationist policies. South Korea (officially the Republic of Korea), in contrast, is a democratic country with free elections, a free press, and a highly developed economy. While South Korea has its own societal challenges such as work culture pressures, wealth inequality, and political corruption, it is generally seen as a thriving democracy with significantly more freedoms and international engagement compared to North Korea. In summary, if "bad" refers to lack of freedoms, repression, and widespread human rights abuses, North Korea is generally labeled as such. However, South Korea also faces typical issues of modern capitalist societies, so the question itself may be too simplistic and misses the complexity of comparing two very different political and social systems.
