An ex-con butchers dozens of people on a vengeance spree. Four ranchers, at least one of them a killer, buy and sell women like cattle. An actor disguises himself so he can peek into the soul of, and learn how to romance, the woman he likes. A robber beats the woman he loves. A kid takes advantage of an acquaintance’s suicide to launch himself to fame.

These are not headlines from the Star Tribune homepage. They’re the plots of musical theater classics. Many — including the above examples of “Sweeney Todd,” “Oklahoma!” “Tootsie,” “Carousel” and “Dear Evan Hansen” — feature characters who behave astonishingly badly. From “My Fair Lady” to “American Psycho,” musical theater is jam-packed with tyrants, maniacs and creeps. (See our ranking of problematic protagonists here.)

The Tony Award-winning “Dear Evan Hansen” opens Wednesday at the Orpheum Theatre in Minneapolis. When it began performances on Broadway three years ago, it touched off debate about its title character, inspiring message-board threads called “Evan Hansen is a sociopath” and “Evan Hansen is NOT a sociopath.” Its title character, a high school student with an anxiety disorder and other mental illnesses (played by Ben Levi Ross), meets a fellow student who dies by suicide. Through a series of mix-ups and lies told by Evan, the student’s note appears to identify Evan as a hero whose compassion almost saved him. The note goes viral, turning Evan into a social media superstar and forcing him to tell bigger and bigger lies.

It seems clear that Evan Hansen falls in the “not” category, sociopathically speaking. Evan’s youth and illnesses make him a sympathetic figure, ensnared in events that escalate so quickly there’s no time to set things right.

Other musical maniacs are not so benign.

Men behaving badly

The purest musical sociopaths were created by Stephen Sondheim, starting with perhaps the most malevolent (and yet oddly relatable) character in all of musical theater: Sweeney Todd. Sent to prison on trumped-up charges, the so-called “demon barber” returns to London bent on revenge against the judge who sent him away and who also is indirectly responsible for the death of Sweeney’s wife. While Sweeney waits to slit the judge’s throat, he practices on the throats of seemingly half of London.

Although they’re less prolific, the killers in Sondheim’s 1990 show about president-murderers are arguably even more psychotic because they believe they’re in the right. “Assassins” is a complex piece of theater, but one reason we have compassion for its title characters is also true of “Sweeney Todd”: In a world gone mad, madness is an understandable, even logical, response.

“Tootsie” does not get off so easily, since the lead character is motivated by selfishness and ambition. Based on the 1982 movie comedy, “Tootsie” opened in April on Broadway, with University of Minnesota/Guthrie Theater BFA actor training program alum Santino Fontana playing Michael Dorsey, an abrasive actor who helps a female friend prepare for an audition and realizes he would be perfect for the part — if only he weren’t a man. So he dons women’s clothing, changes his name to Dorothy Michaels (aka Tootsie) and gets the part, gradually suggesting rewrites that shift him from a supporting role to the main character. During rehearsals, he also spies on the show’s female lead, pumping her for info on what she likes in a man, gathering intel he can deploy at some point, when he’ll reveal that he’s really a man who has been up-close stalking her for months.

It gets worse. Today’s “Tootsie” attempts to grapple with the #MeToo movement, which it specifically cites, and with strides made by women since 1982. But that feels like lip service, particularly when you consider that “Tootsie” is about a man who: A) steals a role from his female best friend, B) shoves aside the show’s leading character in favor of himself and C) announces that he wants to be a spokesperson for all the women of the world who feel invisible.

Sorry, Tootsie, but no. The lead character’s speech at the end of the new Broadway adaptation doesn’t sound like enlightenment; it sounds like mansplaining. It’s pretty gross to plead for the visibility of the very women you just worked so hard to erase.

Incredibly, “Tootsie” is not the most sociopathic musical on Broadway. Not by a long shot. That honor goes, perhaps surprisingly, to “Oklahoma!” now on stage in a provocative rethinking that foregrounds the misogyny and violence at the core of the 1943 musical. The story always ended with a town full of Oklahomans agreeing to let leading man Curly get away with murder, supposedly in self-defense. (Mild spoiler: In the new take, it’s not self-defense and Curly ends the show splattered in the dead man’s blood.)

Even before that, the only interest “Oklahoma!” shows in its female characters — including spirited businesswoman Laurey — is which men they’ll end up with. That becomes clear in the creepy lunchbox social scene, where Curly and a traumatized Jud bid for a date with Laurey. And where Ali Hakim and Will bicker over how much they’ll pay to literally buy Ado Annie from her father.

Beacons of goodness

Obviously, there’s a dramaturgical reason for these problematic musical theater men (and a gender reason, too — with exceptions such as Mary Rodgers and Betty Comden, most classic shows were written by men). Conflict is the essence of drama, and the show’s heroes must have flaws so they can be redeemed.

But it’s worth noting that it’s almost always the men in these musicals who get to have flaws. And it’s almost always the love of a good woman that redeems them. Which is to say: Women are not in the shows to be compelling characters with their own dilemmas, but to shine beacons of goodness that help their boyfriends become better people.

And when women are at the center of a classic musical, they’re usually appalling creatures who never get redemption (Mama Rose in “Gypsy”), dames in pursuit of marriage (Dolly Levi in “Hello, Dolly!” Mrs. Lovett in “Sweeney Todd”) — or, on rare occasions, iconoclasts who live life exactly the way they want to (“Mame”) or problematic people redeemed by the love of a good man (“South Pacific”).

“Dear Evan Hansen,” it should be said, does well by its female characters, particularly Evan’s mother, Heidi. Admittedly, we don’t know much about her outside of her relationship to her son. But at least the show explores why that’s the case, depicting a single parent whose teenager needs more care than a lot of kids his age. (On Broadway, Rachel Bay Jones won a Tony as Heidi, who is played on tour by Christiane Noll.)

In fact, Heidi Hansen is so interesting, with so many parts of her story remaining hidden to the audience, that I bet I’m not the only one who saw the musical and thought: Maybe Evan’s mom deserves a show of her own?
