To show his dominant alpha part of character. He is aggressive, violent, and a bit unpredictable. There is a reason why they call him crazy dog. The manhwa adaption even left out that he bit off the tounge of another actor who provoked him.
Chase is a bit like Keith, who also has anger issues, is short tempered.

Keith Pittman, the author's trash king from "Kiss me liar". He is the boss of the production firm Chase is shooting a movie for and Grayson's friend.
I mean anger issues only, because in other aspects you can't compare innocent Chase to trash like Keith (Keith refered to himself as trash in the side stories.lol).^^
Am I the only one that is still bothered by the almost killing part? He's alive just because the gun was out of bullets
