Su Qin
Thereafter, Su Qin managed to drive a wedge between Qi and Zhao. Qi wiped out Song, which severely weakened Qi such that the Vertical Alliance of the other five states attacked. When Yue Yi defeated Qi, King Min of Qi adjudged Su Qin guilty of dissention and had him torn limb from limb in public. Afterwards Zou Yang said "Su Qin trusted nothing under heaven but he kept his promises to the State of Yan. Sima Qian also commented, "Su Qin undertook a strategy of sowing dissention which led to his execution and all under heaven now mock him".
