You can´t get out of an evil influence that you cannot recognize.

So, first lesson about evilness: Recognize the deception. Evil doesn´t look like evil, instead it looks like good. People doing evil are not stupid, so they know they will not catch attention by showing themselves evil or coming up with an evil agenda. The Evil is presented as beauty, safety, luxury, good taste, justice and trustful.

The deception and manipulation are the main ingredients in Evilness to make the bad thing look like the good thing. The Demons masquerades as Angels of Light. So, it is more expected that Evil shows up like a helping hand instead of a hitting fist. Evil controls the Ignorant. The best way to control somebody is to let the person be clueless that he is being under control. Evil makers try to eliminate the foundation under your feet. People with faith in traditional religions, culture and philosophy are being harassed for being ridiculous and old fashioned. Evil standards give you modern alternatives performed as the best. Nice looking glittering charming alternatives, unproved deceptions out of date in short time. Then, you have lost both the previous stability and the modern trend which rised and fell in short time. 

If you are blind to good beliefs, you are also blind to Satan. And the offers from Satan is always much more tentative and comfortable, than following the right way which right from the beginning shows you the hard sacrifice you must invest much time and concentration in. The Evil alternative is always easy and fantastic. In the beginning. Until the bitter end comes.   

The evil sometimes looks invincible. In service of Evilness is the wealth, the best technology, the best weapons, the Justice, the organized crime, the strong currency and the most skilled professionals. What can any spiritual belief do against all that material resources?

If you add Time to this question, you soon realize that any material things, including body, parents and friends, are temporary illusions. The invisible and eternal life spirit under the rules of the Creator survives and will always win over the delusive materialistic circus.
