Yes, I do agree some regimes are pure evil, often based on hedonistic desires of their leaders. I would class North korea and to some extent, syria in that. I think the regime has handled the protests too brutally. However, there is no need to start any insurgency. The democratic process should be reflected and followed.

Regarding physical Jihad, I think the Koranic morals should prevail. Only on self defense and not terrorism or aggression.
