Bartemius "Barty" Crouch, Jr. (gone undercover as Dark Wizard hunter Alastor "Mad-Eye" Moody) is the main antagonist of the fourth Harry Potter book, Harry Potter and the Goblet of Fire and its film adaptation. He is a Dark Wizard and an infamous Death Eater.
His loyalty to Voldemort is ultimately just fanaticism and he is not protective over him in any way, nor even caring for what Voldemort wishes, as Barty tries to kill Harry in spite that Voldemort always told the Death Eaters that Harry would only be killed by him.
However, Barty did something that proved he was a powerful wizard as he somehow defeated Mad-Eye Moody. Mad-Eye is one of the most powerful wizards in the Order of the Phoenix, and if Barty was able to capture and imprison him, he had to have some talent up his sleeves.
Throughout the series, he is an anti-hero due to overly-cautious and paranoid side when it comes about his personal security, but anyone who dies fighting Lord Voldemort himself isn't a villain, that aside even though Moody may look crazy as all heck but he's not a bad guy.

Why was Moody killed off?
Moody, who was also prepared for every type of dangerous situation, became the first victim in Deathly Hallows: Part 2. Mad-Eye Moody's death only occurred because of a betrayal, which makes it incredibly harrowing. However, Moody's death, ironically, is also the result of his own talent.
He's the newest Hogwarts Defense Against the Dark Arts professor, a rough and aggressive man hiding a big secret. After the Triwizard Tournament, Dumbledore, Snape, and McGonagall figure out that he's Barty Crouch, Jr. in disguise, a sadistic and clever Death Eater on a mission to bring Voldemort back to life.
No, he could not have saved Barty Crouch Jr., not without entering Hogwarts and exposing himself. Not only this, but he wouldn't have thought he needed to save him. For all Voldemort knew, Barty's role in the plan was still going flawlessly.
The film version of Crouch has been described by some as more evil than his book version. In the film, Barty is a fanatical follower of Voldemort out of sadism, when in the book he was neglected and abused by his father and that was a reason he was seeking a father substitute in Voldemort.
His hatred of these sorts of Death Eaters probably stems from being locked in Azkaban for years for his service to Voldemort while others, like Lucius, walked free.
In the film version, Barty Crouch Jr. has the habit of licking his lips when threatened, in a snake-like way, to which he occasionally shows while under the disguise of Alastor Moody. This action led to him giving himself away to his father following the second task of the Triwizard Tournament.
The silver hand Lord Voldemort had given Pettigrew interpreted his hesitation as weakness and/or disloyalty, and strangled him to death, saving Harry and finally finding redemption for his treason, despite his reputation remained tarnished as many remained dubious of the evidence of his innate bravery.
Crouch Jnr, in turn, hated his father, considering him to be a very disappointing parent. Being sent to Azkaban for one year and imprisoned in his own mind for twelve only increased the friction between father and son.
In 1994, Moody accepted Dumbledore's offer to teach Defense Against the Dark Arts for a year, but was captured and imprisoned by Barty Crouch Jr., who impersonated him during the 1994–1995 school year, in order to send Harry Potter to Lord Voldemort.
Thanks to his up close and personal experience with the Dark Arts, Barty Crouch Jr. was actually able to teach the class at Hogwarts somewhat successfully. While he might not have been the most sensitive professor to his students, he effectively got the message across that some spells aren't to be taken lightly.
Bartemius Reginald Crouch Jr. (b. October 1, 1962) is a pure-blood wizard and former member of the Crouch family. He attended Hogwarts between 1973-1980 and was sorted into Hufflepuff house.
Although Crouch eventually escaped, he was murdered by his own son when he attempted to warn Harry Potter and Albus Dumbledore of what had happened. His son felt like Barty Snr loved his wife more than he had ever loved his son, but this was only the truth in the son's eyes and not necessarily the accurate truth.
Personality. Draco Malfoy is the typical spoiled child and bully; he is narcissistic, arrogant, and cowardly. Draco obviously believed himself above everyone else and his parents continuously spoiling their child did not help him.
The main reason is that Lucius failed to retrieve the prophecy from the Ministry of Magic, put that on top of all the other times Lucius failed, and it leads to him losing any clout he once carried within the Death Eaters. Lucius did that for his own benefit - he was trying to discredit Arthur weasley.
Barty Crouch Snr owned a cloak as well, hiding Barty Crouch Jnr under one when helping him escape Azkaban. He was then forced to wear the cloak in the house when he was controlled by Barty Crouch Snr under the Imperius Curse.
What happened to Barty Crouch Jr. after he was caught?
Summary. The Harry Potter movies made a mistake by not including Barty Crouch Jr.'s death, which was a significant difference from the books. Barty Crouch Jr.'s fate in the books was different from the movies, where he died from a Dementor's kiss. In the movies, he was taken to Azkaban and never seen again.
Having devoted his entire life to catching dark wizards — with high ambitions of becoming Minister for Magic one day — Crouch Sr. disowns his son in front of the entire Wizengamot despite his desperate pleas. He uses his son's trial as a public example of how Death Eaters should be punished: a life sentence in Azkaban.
Harry describes Umbridge to Sirius Black, saying that she's vile enough to be a Death Eater, despite not being one. Umbridge is also depicted to be a prejudiced person, despising half-breeds and Muggle-born witches and wizards to the point of firing Hagrid due to his half-giant birth status.
In July 1997, Moody was killed by Lord Voldemort during the Battle of the Seven Potters. Moody's corpse was recovered by the Death Eaters, and his magical eye was somehow taken by Dolores Umbridge, who used it to keep track of her subordinates in the British Ministry of Magic.
Voldemort fired a Killing Curse when Mundungus Disapparated, and hit Moody in the face, killing him. Moody fell backwards off his broom, and about a thousand feet to the ground. Because half a dozen Death Eaters were on their own tail, Bill and Fleur could do nothing.
