Skyfall wasnt Bonds finest hour as an agent. His age and years of injuries were catching up with him and he failed nearly all of his mission objectives, including protecting M from the vengeful Silvia. Even if he wasnt feeling himself none of this excuses his attitude to the death of poor Severine. Severine was Silvas mistress and a former child prostitute who Bond used to find Silva's secret lair. Silva then takes Bond for some friendly target practice, placing a shot glass filled with expensive scotch on Severine's head. Bond is forced to take a shot and misses, only for Silva to coldly execute. Bonds response to the death of the terrified woman he used to complete his mission? That's a waste of good scotch. Maybe he was just trying to act neutral so he could launch a surprise attack on Silvas men moments later, but he never expresses regret or acknowledges her death afterwards. He usually has a cold attitude towards women but this troubling moment left a bad taste with many in the audience.
