He did not love anyone, and did not care to be loved. He felt nothing for his family, and only wanted his friends in school to rally around him because he wanted to hold power over them. Bellatrix Lestrange was obviously in love with him and worshiped him, but he only cared for her servitude, not her.
Voldemort was incapable of love because he was conceived under a love potion, so whatever he felt for Bellatrix, it wasn't love. She was his best Death Eater, and he may have respected and liked her more than anyone else in the world. What he felt for her was probably the closest thing to love that he would ever get.
Before her death, Bellatrix secretly gave birth to an illegitimate daughter named Delphini, whom she conceived with her beloved master, Lord Voldemort. Delphini was conceived sometime after the Battle of the Department of Mysteries in 1996 and before the Skirmish at Malfoy Manor in 1998.
Bellatrix, herself a case study in the Dark Tetrad personality traits (narcissism, Machiavellianism, psychopathy and sadism), is drawn to those traits in Voldemort. She sees Voldemort as the only person worthy of her devotion. He is the only one who surpasses her in power, cruelty and ruthlessness.
The 'boy who lived' aka Harry Potter, aka Daniel Radcliffe had a crush on Helena Bonham Carter, who starred as Death Eater Bellatrix Lestrange in the film. During the reunion, Daniel revealed that he had a crush on her and even wrote a letter to her.
That's right! You heard me- their daughter. For those unaware, in the Cursed Child (which was written for a POST Harry Potter world)- it's revealed that at one point in time, Bellatrix and Voldemort conceived a child of their own- Delphini.
When was Bellatrix Lestrange pregnant with Voldemort's child? So we all know by now that Delphi Diggory ain't Delphi Diggory. Nope, she's the child of Voldemort and Bellatrix Lestrange, who was born at Malfoy Manor just before the Battle of Hogwarts.
His reaction to Bella's death was akin to his reaction at the loss of the Cup, which was when he realised that his own immortality was jeopardised amidst war and his own death could have been near.
Bellatrix Lestrange Killed her own cousin, Sirius Black: She killed Sirius (who was her cousin) during the battle at the Department of Mysteries. She was remorseless and was cackling in glee after she had murdered Sirius.
As much as Bellatrix loves Lord Voldemort, she equally hates Harry Potter, considering him the greatest threat to Voldemort and his plans. She will do anything to assist the Dark Lord's desire to defeat Harry.
Harry Potter and the Deathly Hallows
In this book, Rowling reveals that Bellatrix is the guardian of Helga Hufflepuff's cup (though she is unaware that it is a Horcrux), which Voldemort has entrusted the Lestranges to keep in their Gringotts vault.
Delphi was conceived from a liaison between Voldemort and Bellatrix. She was born at Malfoy Manor, shortly before the 1998 Battle of Hogwarts. As Bellatrix and Voldemort were both killed in the Battle and Bellatrix's husband Rodolphus was imprisoned at Azkaban, Delphi was raised by Euphemia Rowle, a Death Eater.
The most speculated reason why Voldemort wanted a child is that he needed a backup relative to help him create a new body. Voldemort is immortal, but it would only take a stray curse to destroy his body and send him back to the pathetic state he was living in before the events of Philosopher's Stone.
Bellatrix had a fear of rejection as well where Voldemort was concerned, wanting nothing more than to please him but was always frightened that she would lose his favor.
With all of those symptoms being met, it wouldn't be unreasonable to consider her as having a borderline personality disorder. Bellatrix Lestrange “was obsessively in love with Lord Voldemort, which extended to her being… attracted to him” (wiki).
Tom Senior was loved by Merope, who became obsessed enough to use a Love Potion on him. Tom M. Riddle was obsessively loved by one of his Death Eaters, Bellatrix Lestrange. Bellatrix was so eager to please him that she would 'prune' her 'family tree' by murdering her niece.
Helena Bonham Carter said that her character was afraid of Harry because she couldn't understand how a young boy was capable of overpowering Lord Voldemort.
Voldemort's attempts to trick Harry into killing Bellatrix would have done far more harm than good to his sinister cause, as Harry killing Bellatrix might have resulted in dire consequences for him, but he'd remain one of Voldemort's greatest threats and the Dark Wizard would be missing his most trusted lieutenant.
He endured horrible things right from his unpleasant childhood, the death of his best friends to spending twelve years in Azkaban. His tragedy however didn't stop at his framing and imprisonment. Sirius met an undeserving death at the hands of Bellatrix Lestrange during the Battle of the Department of Mysteries.
Why doesn t Harry use Avada Kedavra on Bellatrix? Harry didn't use that spell because he cannot bring himself to kill anyone. He is not a killer.
The author explicitly states that both women were fighting to kill, despite Molly refraining from casting the Unforgivable curse Avada Kedavra. The result of the duel actually comes about as a result of nothing more than spectacular accuracy on Weasley's part.
Voldemort can not comprehend love, and so it destroys him to touch Harry because Lily's love for her son runs through Harry's veins and body. ems Harry burnt Quirrell's face when he touched it.
He did not love anyone, and did not care to be loved. He felt nothing for his family, and only wanted his friends in school to rally around him because he wanted to hold power over them. Bellatrix Lestrange was obviously in love with him and worshiped him, but he only cared for her servitude, not her.
Delphini "Delphi" Diggory is Voldemort's secret daughter (wow, the Potterverse is turning into a soap opera). She wants to resurrect the Dark Lord—not necessarily to bring evil to the world, but just because she wants to meet her dear ol' dad. It's actually kind of sweet…in a completely evil way.
After being on the run from a bunch of Snatchers, the gang were taken to Malfoy Manor, where Bellatrix proceeded to torture Hermione using the Cruciatus Curse. It was a testament to Hermione's toughness that she was able to walk away without lasting damage.
