I mentioned before the Sherlock series. I want to note the last episode of the previous year, as it is a study in evil. This is the episode wherein Moriarty and Sherlock meet "on the falls", in this case on top of a building.
But, the study in evil is what builds up to Moriarty's suicide and Sherlock's apparent demise, which we all know, is orchestrated.
Moriarty begins a campaign very sneakily to undermine Sherlock's reputation as a good person, bringing justice into the world. That the villain succeeds in telling the whole world that Sherlock is a fraud and has set up murders, kidnappings, etc., in order to create a mythology about his prowess is owing to one thing. The latent evil in others allows them to believe evil of Sherlock. Now, the evils vary, the vices are personal to those who capitulate to Moriarty's Satanic plan.
For one person, it is envy. For another, it is pride. For another, it is hurt and revenge. Dr. Watson is the only one who believes in Sherlock to the end, as he is honest with himself about his own lack of perfection. Only those who are pure in heart can think good of others. This does mean that we do not have discernment. But, it does mean that we judge others according to the evil in our own hearts.
The object of the journey of perfection is purity of heart. If we have discovered God in our own hearts, then we see with the eyes of Christ.
To put on the mind of Christ is our goal. That the evil genius succeeds so easily is why men like Hitler and Stalin succeeded in heinous crimes. Evil cooperates with evil and good cooperates with good.
