Perhaps it would help to expand on the character a little bit.
As I said earlier, when she was younger she was sort of like Sakaki from Azumanga Daioh...tall schoolgirl, and a Broken Bird
(in her case because of massive Survivors Guilt).
Now, in terms of appearance and role, she is something like a psychotic, borderline Complete Monster
version of C.C. from Code Geass
I'm still deciding where her Moral Event Horizon
took place, but I am getting ideas from Umineko. They will be suitably horrifying, as evil really should neither be sexy nor cool.
One specific incident: She once became an advisor for a kingdom. She did so in order to get closer to the Princess (a Lawful Evil Well-Intentioned Extremist
), who she could sense had a special destiny. When the time was right, she convinced the King to justify his exploitation of natural resources by starting a 'just' war with a neighboring country. This set into motion events that led to what she wanted; the Princess had revolted against her father and his monstrous deeds, and she became the Queen, only to leave the throne in the hands of a steward.
The villain convinced the now Queen that if her father was a good and decent man, he would never have been swayed by her to begin with, therefore she is not to blame for leading him down that road. The Queen, not really having her head on straight, accepts this logic.
If anyone wants clarification, go ahead and ask. I just don't want to end up describing the entire setting all in one post and wasting everyone's time. :p
But yeah, basically she does 'delegate,' but argues the lack of responsibility to sway those who are more noble.
