Del: " As for Bellatrix, may I point out that we don't know anything
of her back story ? In particular, we don't know what her
relationships with the Longbottoms were prior to the Torture scene.
Frank Longbottom was an Auror, and as such a direct enemy of
Bellatrix the DE. He even had the right to use the Cruciatus Curse on
her, and we don't know if he had any moral concerns such as Moody 
had."

Jim Ferer responds:
Is this Bellatrix Lestrange's defense? If we knew her backstory,
might we find a reason to absolve her? If she has a defense, I suppose
it might be insanity. You can find similar folks up in the Kirby
Forensic Psychiatric Center, sure enough.

vmonte comments:
I have to agree with Jim here. Bellatrix is in league with Voldemort. 
She is cruel, insane, vicious, and filled with hate (not Harry). As 
I've mentioned before she is trying to kill Harry (and others) during 
the MoM scene. Harry is justified in trying to defend himself.  I do 
think however that Harry has many trials ahead, and he will need to 
control his emotions more.
