Evil leaders exist in our world. In fact, I read a frightening article in the paper today that pointed to the cruel, heartless, violence one leader in our world is promoting. The article is too frightening to reference. Clearly this world leader will stop at nothing to get his way, and many including young, innocent children are paying the price for his violence, greed, and heartless cruelty. What can the world do about evil like this? How can we protect one another from the violence leaders like that create?
First, it's important to steer clear of evil enterprises as much as possible. The minute a new job or leader begins to demonstrate evil, you should do what you can to get away and report the situation. You don't want to work for or with leaders like that for any substantial time as they'll likely implicate you in their evil plans and efforts.
Then,, when evil strikes, find out who you can report that evil to--what groups work to counter evil like that. Reporting evil events as soon as possible to trustworthy authorities will save many from the grasp of these evil leaders and enterprises while staying silent will only make the situation worse.
Also support leaders and laws that prevent and/or prosecute this kind of evil. Good laws can work to mitigate the evil that may rise.
The longer we let evil leaders rule, the more hardship there will be. We must work in every way that we can to safely and peacefully (if possible) remove evil leaders from the power they use to hurt people and the planet. We can do that.
