If I ever make a movie, I will have a minor character that's just like a nice background character you see every so often, one that's just a sort of friendly face for the protagonist without really having a big relationship with them or role in the plot.
Then I will have that character murder someone in full view of the protagonists and the supporting cast. It will be a minor character, no one the audience knows and isn't really relevant to the story. Maybe relevant thematically, if they're lucky, but otherwise, nothing.
Then the rest of the movie will continue without commentary on the murder. The background character will still be that smiling, friendly, wholesome presence that the protagonist throws a line once in a while, as normal.
And then I will watch in satisfaction as I see the think pieces of "Someone should have done something about that one background character, because murder is bad" roll in.
