UNMARKED SPOILERS AHEAD
When playing thorough Assassin's Creed: Syndicate, both Jacob and Evie Frye have missions where, within them, they take out a special target (usually one of Starrick's more prominent henchmen). After they do them in, a certain scene follows where the background goes white (similar to the loading screen), the killer talks with their target as they lay dying, then they wipe blood off the dead with a white handkerchief.
Example: When Evie kills Lucy Thorne (ends about 3:29).
However, in the scene where
He doesn't wipe the blood with the handkerchief. Why? And what is the greater symbolism and purpose of these "death scenes?"
Side note: if this is also present in other Assassin's Creed games or was explained then, it is outside of my knowledge because Syndicate is the first Assassin's Creed game I have played.
