History Characters / TwentyFourChina

* EvilCounterpart: Like Jack, he's a highly efficient agent who commits some morally questionable acts in the name of getting the job done. While Jack [[EveryoneHasStandards has certain lines even he won't cross]] and the harsher decisions he's forced to make are never ones he does so lightly, often being shown to weigh heavily on him, Cheng is an out and out sociopath who can and will play dirty any way he gets without a hint of remorse. [[spoiler:Gets taken UpToEleven as of Day 9. By ''Live Another Day'' both men have gone from being top agents for their respective governments who did what they thought was the best for them to ultimately being declared to be traitors and abandoned for committing extremist acts. Despite his own disillusionment, Jack's sense of right has been helping him working his way toward redemption, coming out of hiding to protect Heller even with his own freedom on the line rather than let millions of people die. Cheng on the other hand now sees his all of China as his enemy for daring to turn its back on him, ultimately choosing to attack it in addition to the U.S.]]

* FauxAffablyEvil: He always has a polite tone that brimes with cruelty or condescendance.

* TheSociopath: Oh sweet mother of heaven yes. Even before [[spoiler:his own country labelled him a traitor]] he didn't care whose lives he ruined in order to get his job done, and after being apprehended while working with a known criminal like Philip Bauer, he legitimately thinks his government would stick by him regardless of his actions due to how much of a loyal enforcer he's been, [[spoiler:which [[RealityEnsues they ultimately didn't]].]] [[spoiler:And then after going rogue, he's willing to start a war which would have resulted in the deaths of millions of people to settle his own petty grudge against China, even though [[NeverMyFault it was his own damn fault that the country turned his back on him]].]]
