The moral degradation of US politics goes back long before Trump arrived on the scene. This was
reiterated by the blogger known as Mike the Mad Biologist:
Time was, in popular culture, torturers were viewed as evil, not as heroes ‘doing what needs to be done.’
The first sentence got me thinking.
It's not hard to find older movies in which torture is shown as unequivocally evil. In
Return of the Jedi (1983), it's a simple and convenient shorthand.
To establish that Jabba the Hutt is nasty and scary, we have a brief shot of a dungeon in which droids are being tormented with red-hot irons. There's no need to stop and explain that Jabba is a Bad Guy Torturer, as opposed to a Good Guy Torturer. He orders torture, so by definition he's evil. We can move swiftly on and watch Luke fight the Rancor monster.
Newer films, by contrast, tend to be more ambivalent about torture -- if not openly endorsing it as Okay When A Good Guy Does It.
The examples I'm going to use are a couple of light-hearted comedies. They aren't extreme cinema, setting out to break taboos and push the portrayal of violence to its limits. They're films in which torture is present and important, but tangential to the main story. As such they may be a better representation of mainstream beliefs.
Consider
The Princess Bride (1987), which as most of us know includes "fencing, fighting, torture, revenge, giants, monsters, chases, escapes, true love, miracles."
