Let this be burned into everyone's memories. What people fear is not violence. What people fear is change.
People are fine with getting the short end of the stick, if it means they get to continue their lifestyle a little longer, regardless of whether or not they would be better off with change. The ultimate tool for change is violence, and so among other reasons it's easily met with criticism and protests. Many prisoners are content with staying prisoners. Many people in North Korea or China are content with living their lives completely dominated by their governments. If a foreign military decided to overthrow North Korea's dictatorship, their own military would fight to the death to protect it. Many of them might agree with that foreign power, but it would be change, which is absolutely something that they have to defend against.
Change is risky. Change is uncertainty.
People don't remember history. The national "reset button" doesn't mean anything to them. All it means is that there's going to be a greater change tomorrow if the coup is successful, than if Ergodan is still in power tomorrow and decides to end the lives of anyone involved in the coup. You could argue about morals all day, but morals aren't the deciding factor here.
In the end if you're a radical Islamic terrorist with a heart of gold, laying down your suicide bomb vest and living a peaceful life is scarier than dying.
