How To Fix Evil

Certain troubling regimes such as North Korea and Russia or Mexican drug cartels exist. To solve this, understand that: first, those regimes are problematic at the leadership level, as the regular people are just people; and 2, if big problems are not getting solved then apprently people don't want them solved.

Of course it's not black and white and from the sociology perspective we must see that it's a mix. The grade between pure good and pure evil is a complete gradient, and the balance comes out to general good as the world today is quite an amazing place.
