Rotten Little Devils

An Angel in Heaven decides to transition into a demon, because he can see that on Earth, the battle between good and evil is being won by evil, and he wants to be on the winning side.

He abandons the security, comfort and bliss of Heaven and heads for Earth, the kingdom of the Devil himself, where he is mentored by a demon with thousands of years' experience in deceiving and hurting people. We get an inside look into his training as his ancient guide teaches him how best to influence people to bring about loss, illness, anguish, and destruction upon themselves.

Devils can never overcome people s free will, but they are nevertheless persistent in their never-ending efforts to subvert, undermine and wreak havoc through their deceitful and beguiling ways.

Is this a true story?
