Carrie Hartnell Cutter (born November 21, 1987), also known as Cupid, is a former police officer of the Starling City Police Department.For a time following her police career, she became obsessed with The Arrow and practiced archery. This obsession escalated and she began killing/threatening people in an attempt to get his attention. However, after he took her down, she was taken in by Amanda Waller as a part of the Suicide Squad. After getting back in society she started to hunt down recently married couples before she got stopped by Team Arrow.
Seemingly playful and flirtatious, she is revealed to go to extreme lengths to satisfy her desire to be with The Arrow, including killing. Becoming obsessed with the Arrow she seemed to build her entire world around him, and only focus on him. Explicitly stating she did not touch Roy and even kill the hacker after he tried to get intimate with her. Believing that they were meant for each other, she referred to Oliver as her "lover" and "boyfriend". Carrie seemed to ignore laws and moral boundaries alike, killing Isaac Stanzler and injuring two police officers just to get his attention. She even threatened to kill everyone in the club if Oliver did not show up. Carrie is shown to get angry when people confront her with her mental disorder. She claims that there is nothing wrong with her and strongly disliked the psychiatrist that treated her. After Oliver rejects her, Carrie is enraged, and becoming furious, she tries to kill him. In a final act, she wanted to die with Oliver, saying that if she can't have him, then no one can. She tied Oliver to the train rails using hand cuffs. She wanted to die together by being hit by a train. Her illness is furthered when Oliver snaps free and saves her again. Although it was only to keep his promise of saving people and not killing, Oliver's action causes Carrie to believe that he saved her because he loved her.
As a result of put on Task Force X, Carrie's personality and behavior seems much more stable, however she still seemed to believe the Arrow and she would be together. She cheerfully asked Lyla about her wedding and told her in details how she and the Arrow will get married and make babies together. After Floyd Lawton took a bullet for her she became quickly fond of him and seemed to focus her desires on him.
Her psychiatrist diagnosed her with attachment disorder. This refers to a inability to form real lasting relationships. She pushes everyone away and fixates on one single person, that she feels mirrors her emotional state. She desires honesty and sincerity and can notice when people lie to her.
