Kuli was able to get to where he is today because he's a shrewd man. He knows that refusing to confess means death, and confessing won't get him past the Dark Church either—he'll die all the same. Whether he talks or not, the ending is the same, so he doesn't fear any interrogation. How do you threaten a man with death when he already knows he's going to die? But once he realizes he might not have to die, that there's room for a better future, it's different. Kuli's ambition flares to life. He doesn't reject Luo Zheng's camera at all, knowing this is the prerequisite for defecting, and he starts talking freely.
