He went to wipe the painting, because he felt that there was dust on the painting, how could he care.
No one cheered for Rob to kill Jesse, someone was willing to spend money to spend time with Jesse, someone rushed in and killed Rob, no one cared about that. Rob was more of a criminal, killing "heroes".
Jesse was not killed by Rob. It was doomed. He was tired. He saw Rob raise his gun in the painting, but there was no emotion in his eyes.
Two hours and forty minutes of watching the movie, Pitt's acting skills are profound, needless to say.
Suspicion and moodiness are his most direct manifestations. Anyone with him is like walking on thin ice. His eyes can see through everything, a smile, a moment of silence, and the next second will pull out the revolver around his waist.
In the whole movie, Jesse actually only killed one of his subordinates, but Pitt's interpretation and performance of Jesse (including some scenes and soundtracks) made the Jiang Yang thief look like a melancholy ghost, which made people stunned!
