You are wrong - there is no comparison between Mao & Kim.
First, most of foreigners or countries do not hate Mao; most liked him, respected him or afraid of him. Just read all the reports by international press after the news of Mao's passing away. Most spoke very highly of him for his life-long achievement for China, even though some did not like Mao's ideaology. The most influential former US Sectary of State, Herry Kisinger, said he found Mao was the most intellectually challenging leader he ever met. Mao's works are studied in the west, even in West Point in the US.
Do u think any Western leaders would say anything good about Kim after he is gone?
The people who hate Mao are Chinese, most live Taiwan & some Chinese living in the western countries. Because these people were losers in China either in terms of money or their political power, or both.
