So will we come on him in some place where he will be found, and we will land on him as the dew falls on the ground, and there will not be left to him, or to all the men who are with him, even one. Bible

“there will not be left to him … even one.” Ahithophel’s advice included bringing the people back to Absalom, whereas Hushai’s advice was kill all the people who followed David. Since Absalom likely did not trust the people who followed David, getting rid of them all in one battle would seem appealing.
