Cassian Andor was introduced six years ago in the Rogue One: A Star Wars Story and is now the focus of the aptly-titled series Andor on Disney+. In the series, we get Andor's backstory and what led him to the doorstep of the Rebel Alliance, but not everything he does is for the greater good or the most honorable.

Within the first few minutes of meeting Cassian, he kills an informant that was on his side and did the work he set out to do. Mild spoilers ahead, but in the first episode of Andor, Cassian accidentally kills one corporate security member trying to shake him down, but then he very clearly intentionally kills another one who was a witness.

Talking to Entertainment Weekly, star Diego Luna goes into depth on where Andor is at the beginning of the series and the correlation to that and Rogue One, as well as Cassian's easy trigger finger.
