In a study published in the journal Psychiatry Research, French psychologists and psychiatrists determined that Darth Vader had six of the nine criteria used for a BPD diagnosis, as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM): Impulsivity. Rage and anger management issues.
Unfortunately, these needles, which transmit neurological data throughout his body and allow him to control his limbs, also cause him constant pain. Between the never-ending itchiness and walking around with needles in his skin, it's no wonder he is so angry.
The reason he wasn't as aggressive and violent in his fighting style in A New Hope is because of his loss to Obi-Wan in the show. Darth Vader let his anger and hate for Obi-Wan get the best of him twice. One that cost him his limbs and barbequed his body.
Even after his brutal scorching in the fires of Mustafar, sand remained the only natural phenomenon that Vader feared. To him, sand was a reminder that he'd failed to save his mother or Padme from death.
In "Return of the Jedi", Darth Vader is seen shedding tears during the final confrontation between him, Luke Skywalker, and Emperor Palpatine. This moment occurs when Vader witnesses his son, Luke, being tortured by the Emperor's Force lightning, and he is torn between his loyalty to the Emperor and…
“Luke, I am your father.” Despite this iconic exchange occurring in one of the most climactic scenes in movie history, Darth Vader never says, “Luke, I am your father.” In actuality, he says, “No, I am your father.”
It's a mid-atlantic accent he speaks with; it's supposed to give the feel of Vader's high authority and rank, as the mid-atlantic accent was fashionable in the late 19th and early 20th century American upper class.
Obi-Wan faced off against Darth Vader four times and physically beat him twice while beating him through his Force development in a third fight. Obi-Wan Kenobi had the high ground that led to Vader's disfigurement and becoming the ultimate Star Wars cyborg.
After turning to the dark side and joining the Sith, Vader continued to employ Form V. His secret apprentice, Galen Marek, was also familiar with the form, having been personally trained in its usage by Vader.
Vader constantly experiences excruciating pain due to the suit's design. Though he once perceived it as one of the suit's major downfalls, he later came to embrace it as it fueled his rage, allowing him to strengthen his connection to the Dark Side.
While Vader suffered extraordinarily -- physically and mentally -- following his fiery fight with Obi-Wan, he nonetheless gained an aura of command and dread upon his "rebirth" in his infamous and domineering suit. No one ever dared to disrespect him as the Jedi Council once had.
Darth Vader's loss of limbs prevents him from using force lightning, a common ability among Sith, making him weaker in comparison. Vader's reliance on his mechanical suit weakens him in battle, reducing his agility and mobility from his days as Anakin Skywalker.
In the Star Wars Universe, it's hard to deny Darth Vader's greatest enemy was the Jedi Order. Sure, he had enemies such as Qi'ra, the Crimson Dawn and Doctor Aphra. But few came close to truly defeating him, other than Obi-Wan Kenobi and in time, his son, Luke Skywalker.
“You were right about me. Tell your sister... you were right.” Those were the last words Anakin Skywalker, aka Darth Vader, ever said while he was alive.
And he's already murdered Mace Windu at Palpatine's behest, more or less by stabbing the Jedi in the back. The canonical comic Star Wars: Darth Vader #7 confirms the younglings' deaths caused Anakin grief, self-loathing, hatred, and pain, fueling his descent even further into the Dark Side.
Age and resignation. He's matured in many ways, become more patient and restrained. He learned from his defeat, and years of quiet study and contemplation. He's not always at the front anymore, and with no rules to restrict him, he really has no tension.
But Star Wars: Darth Vader #26 reveals that Anakin's hatred of sand doesn't simply come from his life on a desert planet, but from an intense, traumatic moment involving his mother and a near-death experience.
Darth Vader often smiled when he farted. Because he knew no one, including himself could hear or smell it. One of the only positive benefits of his bio/mechanical suit. However, he was arguably the happiest in his life when he tossed the Emperor into that energy well.
Vader's cruelty is showcased through 10 heinous moments, including harming his family, murdering innocents, and causing destruction. From dragging Obi-Wan into fire to slaughtering younglings, Vader's evil actions reveal his commitment to the dark side.
