Evil is a great manipulator, the evil within often convinces people that they are on the path of righteousness, they often make themselves believe that the wicked things they are doing are doing for good!
The conjuror keeps giving them false excuses for serving it, then one day they realize how they have been tricked by themselves, quite often it is good to simply go by the old school, decide whether an action is good or bad, ignoring the “reasons” behind doing something wicked.
Maybe justice can be left in the hand of God, for our own sake! After all, we don’t know everything, we can be absolutely wrong about so many things!
Evil is a good actor too, a very clever manipulator, it can make day look darker than night!
