Rewatch the scene. Shirley takes her finger away from the trigger when Rolo confirms that he's Lelouch's ally (Rolo reacts to this, obviously realizing what it means) and says that she wants to help Lelouch.

Then Rolo considers it for a second and murders her.

He obviously really wanted to dispose of Shirley.

He's a male yandere. One that fully crosses the moral event horizon.
