Bellatrix attended Hogwarts School of Witchcraft and Wizardry and was sorted into the Slytherin House. She eventually married Rodolphus Lestrange — a fellow pure-blood, as was expected of her — and when Lord Voldemort first rose to power, she and her husband joined the Death Eaters. Unlike her sisters, Bellatrix displayed no outward affection for her husband whatsoever, never even mentioning him in conversation. Her true প্রণয় was Voldemort, who gave her some training in the Dark Arts, which contributed to her incredible talent as a duelist.I think because she was in প্রণয় with him,because she was a pure-blood witch purposed to serve in Dark Arts.
Her whole family were Pure-Blood fanatics and opposed others who they thought were below them: half bloods, muggleborns, squibs, blood traitors.
I think its what Bellatrix was taught from a child, being Pure-Blood was everything to the Black Family, respectable lineage and marriage which was expected from her.
In her eyes being a Death Eater would be great, she loved Voldemorte even though i doubt he even returned her feelings (which is impossible as he cant love) and he taught her ruthlessness, deadly combatant, she had this "fear me" about her.
Bellatrix went to hogwarts and became a slytherin. When she grew up she married Rodolphus lestrange who was already a death eater.she became a death eater and realized she had a stronger affection for voldemort.After that she dovoted her life as a death eater just to please him.
Becuase She went to Hogwarts and was sorted into Slytherin, like most of her family. And every Slytherin never turns out to be good. And when Voldemort first rose to power, almost the whole Malfoy/Lestrange family joined the Death Eaters. And Plus, the বই always gave hints that Bellatrix was truly in প্রণয় with Voldemort. So, she always stayed loyal to Voldemort to get his affection and attetion. I was never on the Death Eaters side but she was the best and most loyal Death Eater there was.
ARE আপনি KIDDING ME? I can't believe আপনি asked that. It's cleear she did because she was jealous of Sirius Black, man. If i were a death eater like her i would kill Sirius Black and rule the world. And i would defeat the dark lord and rule the death eaters for myself!
