David commits random acts of genocide for the Philistines

In 1 Samuel 24, David snuck in and cut off Saul's skirt while he (Saul, that is) was defecating. And Saul didn't even notice.

Yeah, well, that worked out so well for David that he decided to try something like it again. This time, though, he snuck into Saul's camp and stole his sword and water jug while Saul was sleeping.

So David and Abishai came to the people by night: and, behold, Saul lay sleeping within the trench, and his spear stuck in the ground at his bolster: but Abner and the people lay round about him ... So David took the spear and the cruse of water from Saul's bolster; and they gat them away, and no man saw it, nor knew it, neither awaked: for they were all asleep; because a deep sleep from the LORD was fallen upon them. 1 Samuel 26:7-12

Not nearly as impressive, I'd say. Especially when you consider that "a deep sleep from the LORD was fallen upon them." That sounds like cheating to me.

But Saul went gaga over it, just like he did for David's last trick. Here's what he said when David waved Saul's sword and water jug in front of him.

I have sinned: return, my son David: for I will no more do thee harm, because my soul was precious in thine eyes this day: behold, I have played the fool, and have erred exceedingly. ... Blessed be thou, my son David: thou shalt both do great things, and also shalt still prevail. 26:21-25

But David still didn't trust Saul, so he decided to join up with the Philistines. And every day he and his men would go out and slaughter people. The Philistine king would ask him, "Hey David, who'd you slaughter today" and he'd say, "Oh the south of Judah, or the Jerahmeelites, or the Kenites, or the Geshurites, or the Gezrites, or the Amalekites, or the Egyptians."

And David and his men went up, and invaded the Geshurites, and the Gezrites, and the Amalekites ... even unto the land of Egypt. ... And Achish said, Whither have ye made a road to day? And David said, Against the south of Judah, and against the south of the Jerahmeelites, and against the south of the Kenites. 27:8-10

He was a killing machine. Every day he slaughtered thousands of people for the Philistines.

And David saved neither man nor woman alive. 27:11

So the Philistine king, Achish, loved David because David killed Israelites along with everybody else.

And Achish believed David, saying, He hath made his people Israel utterly to abhor him; therefore he shall be my servant for ever. 27:12

(David brags about at least six genocides in 1 Sam 27:8-10. So I'll add another 60,000 to the total, 10,000 for each genocide.)
