The reality is very simple, there is no evil only an illusion / or illusions that are self-imposed, then played out in personal mind.

As for the entire good vs. evil, there is a law/ divine Law or the Law of Creation that lives in anybody heart. When person is aligned with this, they are ok, living their truth and life, when person steppes out of line and lives with no respect in his/her heart, things around this person will start happening to help this person to realize and they will be happening untill this person gets it. It is like this for every one of us – no exceptions.
