[General] What individual has the highest kill count ever?

I was reading about a galaxy far far away in my local achieves and read about an individual named Luke Skywalker. He destroyed a massive star ship in one strike, killing many. 

It got me thinking, who has killed the most, for good, evil, one attack, and over time?

Under Lord Rassilon of the Time Lords, trillions died each day, only to be reset and killed again. He's also responsible for the Great Vampires, who consumed entire species, the destruction of entire star systems, and who knows what other atrocities. He's a generally unsavory chap.
