I swear to you I could do better than Kim Jong Il. I would start by allowing free speech, criticism of the government. That alone would make me a better leader.
Yes, true armchair general here. Do you really think it would do good to make such radical change? Hell, it doesn't even work for China. The people won't accept that change.
Good example is Thailand where it's unlawful to call the king with names. This while in fact the king himself has said that people should be able to do so and they should be allowed to criticize him. But the people love him and just won't allow that law to be taken off. They want punishment for people who do so, even while the king himself doesn't.
You really need to think effects such actions would do. It seriously isn't just as straightforward as "there you go, free speech to all".
All power corrupts, but we need electricity.
