Bellatrix Lestrange tem algum afeto em relação a Voldemort?

Sim, definitivamente.

Existem muitos exemplos nos livros de Bellatrix mostrando extrema afeição por Voldemort. É retratado como um relacionamento obsessivo e doentio, especialmente porque ele nunca retorna seus sentimentos. No entanto, ela estava definitivamente apaixonada por ele, como confirmado por J.K. Rowling se:

Did Bellatrix ever love her husband, or did she have love only for Voldemort?

She took a pureblood husband, because that was what was expected of her, but her true love was always Voldemort.

— J.K. Rowling and the Live Chat (July 2007)

Uma segunda confirmação da JKR, explicitamente confirmando que o amor dela era romântico e não platônico:

... And Bellatrix, was, as I think is clear-- you know, I doubt that people will be particularly shocked to hear, 'cause I'm sure they've deduced, that Bellatrix is madly, romantically in love with Voldemort.

This is-- you know, that's the obsession of her life. And I believe that Helena Bonham Carter had to be asked to tone it down after she-- (laughs) The producer called me and said, you know, give me some background on Bellatrix so we can tell Helena about it. And I said, well of course, it's a sexual attraction. She's madly in love with this man, and obsessed by him. (laughs) Apparently, they had to ask her to bring it down because she was being a bit too sexy.

De acordo com a mais nova história The Cursed Child , a Bellatrix ganhou mais do que pensávamos anteriormente.

DELPHI: I am from the future. The child of Bellatrix Lestrange and you. I was born in Malfoy Manor before the Battle of Hogwarts. A battle you are going to lose. I have come to save you.

Enquanto Voldemort não ama ninguém, Bellatrix com certeza conseguiu exatamente o que queria.
