As a child of Voldemort could Delphi comprehend love? I believe Bellatrix had the capacity to love.

However Delphi seems more obsessed than motivated by love.

I'd agree- but she was orphaned at only a few months old. Like any child she must have asked about her parents. When she was told who killed her mother- would it be fair enough for her to conclude Molly is 'evil'?

Her own ability to love is questionable as you say- but her ability to make a judgement on her mothers killer- is it valid?

She may, like Voldemort, have held no affection or love for her mother and therefore didn't care about her death.

However if she did deem her mother's murder to be an evil act it would be hypocrisy as Delphi herself was a killer. Unless Delphi considered herself to be evil too which I don't think is likley.

I am good no matter what consequences

All of that is true- and of course it's hard to say exactly how she felt about a lot of things not covered in the script.

I guess what I'm asking is- if Delphi had ended being a 'good' kid- had loved her parents despite not knowing them,- there would be someone who may percieve (wrongly or rightly) that Molly was infact evil- leading back to your original point- Evil is a point of view

Perhaps I shoud have gone with the Sirius example. The whole wizarding world thought he was evil and locked him away in Azkaban. Was he evil? No. But from the 'point of view' of most Wizards. Yes.

Both sides have consequences. If you're on the good side you might die. If you're on the bad side you might die and will also kill many others. But I would have to choose the good side because I believe that the good side is the right side.

Dark I guess

Molly didn't murder bellatrix, she destroyed her. There's a difference. In Order of the Phoenix (book) there is a dialogue for this:

"You do not seek to kill me Dumbledore?" called Voldemort, his scarlet eyes narrowed over the top of the shield. "Above such brutality, are you?"

"We both know that there are other ways of destroying a man, Tom," Dumbledore said calmly, continuing to walk toward Voldemort as though he had not a fear in the world, as though nothing had happened to interrupt his stroll up the hall. "Merely taking your life would not satisfy me, I admit -"

-Order of the Phoenix, page 814, Chapter 36, The Only One He Ever Feared

Then in Deathly Hallows part 2 Molly performed a spell on bellatrix, (which I strongly suspect was the impediment jinx) and it made her freeze. After that she performed another spell that caused her to shatter into a million pieces.

Molly Weasley did not murder Bellatrix Lestrange. Molly Weasley DESTROYED her.
