the remake

Total crap every remake is

The approach you describe is simply not in the cards for any movie made today. The original was made during the '70s, which is called the "auteur era" of film-making. Studios took a very hands off approach and gave directors carte blanche to do pretty much whatever they wanted. This produced a whole decade of gritty, and often very bleak films, as directors were deliberately following a subversive trend that was the opposite of the wholesome, heroic, idealistic films of the fifties and early sixties, which had had unabashed hero characters that audiences were meant to look up to.

In the '70s, you find tons of anti-heroes, like Carter, like Arthur Bishop in "The Mechanic" (note the remake of that movie also makes Bishop less sociopathic), Alex DeLarge from "A Clockwork Orange," Michael Corleone from "The Godfather" movies, Travis Bickle from "Taxi Driver," etc. etc. You simply don't find such unredeemed anti-heroes as protagonists in films today, and you haven't since the 1980s.

This is because the auteur era came to a screeching halt with the failure of Michael Cimino's "Heaven's Gate" in 1980. It went so hugely over budget, and then bombed so epically that it took down the studio that bankrolled it, United Artists, and made the studio executives unwilling ever to allow directors that degree of freedom again. And honestly, you can't really blame the studios after that; they run a business, and they have to make money to stay in business.

So today, studios are more involved. They know audiences like happier endings to stories, and more relatable and heroic main characters, and they almost always insist on that. So you simply won't see frankly sociopathic protagonists like the original versions of Jack Carter or Arthur Bishop in movies made today.
