The Evil One Had A Plan

He would appear before his master's creations and tell them that the universe was a dark madhouse of nightmare where love was alien and that to survive while pleasing their creator they would need to reflect such within themselves, loathing and killing each other, envying and abusing, attacking the world upon which they were born until it was a bleak cesspool landscape that also mirrored the heartless void in which they found themselves.

His hope was that when the creator again turned their attentions to this world and saw what had happened that they would then doubt themselves, being as how this was born from them, and wonder if they should have ever endeavored in the first place.

It was a good plan.
