The Evil One Had A Plan

While his masters were busy with their usual business of sowing their genetic material about the denizens of the planet, he would choose a species to infect with his own questionable donation mixed with those of other troublemakers that had been collected over time.

The intent was that when they returned well into the future and saw the results of the progression of these beings infused with what they would call abnormalities and what he would term wisdom, and not knowing that their original efforts had been tampered with, they must then finally question the validity of their endeavors, which they had never bothered to do before.

It was a good plan.
