@edgarblythe,
I understand your POV. I can trace back to the popularity of the movie Bonnie and Clyde. That’s where I recall that our (over 70 yr olds) modern cinema history the bad guy and extreme violence was glorified and bad guy was the hero. Of course, Bogart and Cagney and Robinson movies did that glorifying too. However, it was nothing like the ones you mentioned… or worse,…movies like Scarface where it was violence just for the sake of violence .
Speaking of Robinson. I recall him in the movie Little Caesar,after being shot, saying the famous line, “Mother of Mercy, is this the end of Rico?”
