Apparently, Umbridge's mother was a Muggle and her brother was a Squib – a source of huge embarrassment for the family. Perhaps their abandonment and retreat back into the Muggle world had such a huge impact on Umbridge that it became the catalyst for her Muggleborn-targeted cruelty later on in life.
"She has an affinity for this horrible object, which would help rather than hinder her" so, the horcrux's negativity actually affected in a good way for umbridge(in her perspective, not us ofc, she got worse!)and made her able to summon a patronus.
Harry was the most outspoken, which often landed him in trouble. She steadfastly stuck to the Ministry line that Voldemort had not returned and that Harry Potter's claims were only to get attention for himself.
That's why Umbridge is so much more hateable; Voldemort ignores the rules to destroy people, Umbridge rewrites them to do it. This. Umbridge is the kind of evil that gets away with it - either because they wrote the rules and enforce them themselves or because they've got the person who does in their pocket.
Although Umbridge was not a Death Eater, and had no direct contact with Lord Voldemort, she showed that she was fairly in line with their goals. This was due to Umbridge's callous nature and her prejudiced beliefs, both of which were similar to Death Eater behavior.
Her prejudiced views toward Muggles were so vile that even Ministry workers with anti-muggle ideologies were shocked by her suggestions of how the non-magical community should be treated. Despised her Muggle mother and her Squib brother, considering them inferior to her and her father under the latter's influence.
Why did Harry's scar hurt when Umbridge touched him?
J. K. Rowling stated that the pain from Harry's scar on his forehead was caused by the piece of Voldemort's soul trying to leave his body through the wound it entered to rejoin its master's soul.
They are just as vile as each other. The key difference is that Umbridge has more control being able to mask her " evil " and be in a government position where as Bellatrix is the person that has been caught and is more impulsive.
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.
Who is the most hated character in the Harry Potter series?
Dolores Umbridge
The most universally hated character from the series has to be Umbridge! She is sadistic and has a tyrannical behaviour as Hogwarts High Inquisitor. She used cruel disciplinary measures and oppressive regulations, which make her the epitome of 'villainy'.
And it would also give us some important and evil Hufflepuff. J.K. Rowling has answered this question with one of her new stories on Pottermore. In her history of Dolores Umbridge, she stated that Umbridge was in Slytherin.
After Harry Potter stood up to Professor Umbridge by giving an interview to The Quibbler, edited by Xenophilius Lovegood, Trelawney showed her support by breaking her usual pattern of predicting horrible deaths for Harry, instead predicting that he would have a long life, become Minister for Magic, and have twelve ...
The only problem is that she tends to overdo it to the point that it's just as disconcerting. All in all, she's an “amazing” (as far as sociopaths go) example. And as Harry points out, she's arguably just as bad as, if not worse than, any Death Eater.
Dolores Umbridge complemented Voldemort's essence well so there really was no negative effect just an expansion on how Umbridge already acted. With the new Ministry, she was capable of expanding on muggle-born hatred and actively create kangaroo courts against muggle-born and half-blood wizards.
When the centaurs made threatening moves, Umbridge cast "Incarcerous" on the centaur Magorian, strangling him with ropes. The centaur Bane then picked her up and carried her away deeper into the forest screaming (what happened to her beyond that, during her time with the Centaur herd until she was rescued, is unknown).
Apparently, Umbridge's mother was a Muggle and her brother was a Squib – a source of huge embarrassment for the family. Perhaps their abandonment and retreat back into the Muggle world had such a huge impact on Umbridge that it became the catalyst for her Muggleborn-targeted cruelty later on in life.
“[Umbridge's] desire to control, to punish and to inflict pain, all in the name of law and order, are, I think, every bit as reprehensible as Lord Voldemort's unvarnished espousal of evil,” Rowling wrote.
If you have only seen the films, you might be surprised to hear that it wasn't Cho Chang who betrayed Dumbledore's Army to Professor Umbridge – it was Marietta Edgecombe. A friend of Cho's and a fellow Ravenclaw, Marietta (reluctantly) joined the DA.
It is assumed Bellatrix was at least initially drawn to Lord Voldemort because they both believe in an ideology that favors pure-blood wizards and witches over other members of the community. This elitism, shared by the Malfoy and Lestrange clans, was instilled in Bellatrix since childhood.
Well, in Umbridge's case, while she may have been working for the bad guys of bureaucracy, she was never under Voldemort's thumb. She was allied with the Death Eaters and definitely enabled them, she was never an official part of the organization.
He was also capable of respect, like he respected Salazar Slytherin, but not love. He valued Bellatirx as one of his Death Eaters who was capable of delivering the results he wanted, but he didn't love her (Maybe he respected her though). Who was worse, Voldemort or Bellatrix?
Notably, Voldemort appeared to be entirely unaware of this split, as he later created a seventh Horcrux in his quest to have six, and continued to target Harry Potter despite him now holding part of Voldemort's own soul.
Hagrid's half-giant status also meant that Umbridge was highly prejudiced against him, viewing him as a "filthy half-breed", and so she became quite determined to get rid of him. Umbridge's biased and insulting inspections of his classes made Hagrid rather nervous, and he was soon placed on probation.
Actually, Umbridge was inspired by one of her teachers. That's how she is written in the books. The idea is to make her as grandmotherly as possible in appearance: all pink, kitten plates, a bow on her head.
