Angelic retribution, and the counterplan

You seethe with anger, deep in thought. You've sensed a powerful divine presence nearby, and it could only be one thing. An Angel.
It's seems that fool God was paying more attention than Master Satan anticipated.

You swoop over to the office building where the "cure" was to be administered from. Your brothers and sisters here are busy preparing to cement their domination of this world. A massive pentacle drawn in the blood of remaining human captives sits in the center of the main lobby. Bloodied skulls with melting candles atop mark the intersections of the sharp red lines. The only true way to make a Hell on Earth is to bring Hell to Earth!

Suddenly, in your head, Raven whispers you a message about the angelic interloper.
"Sister! We've located the Angel. She's perched on the roof of one of the skyscrapers overlooking the city. What should we do?"
"Stay there and keep watching her from afar for now. I've got a plan."
You shout to one of the "artists" who had been drawing the pentacle, and give her and her companions a new task.

Sometime later, you,peek over the edge of the building, looking towards the angel flying up in the clouds. So far no-one had intercepted the winged fool, but that was about to change. You look to the others there with you: Raven, Jenny, and several others who are doing their very best to not resume playing with each other again.
"Alright, you all know the plan. Selena, you go and attempt to draw the angel over here. You know they can't resist the chance to destroy a demon."
The succubus named Selena nodded, and jumped off into the air, flapping her wings and cruising towards the angel.
Jenny's voice entered your head once more.
"We've go to remove this one and complete the summoning ritual before more of these bastards arrive. If they take back Earth before it's fully corrupt, we'll never be able to stage an **** on heaven."

You nod.
"Be patient, Sister." You watch as the angel takes notice of Selena flying towards her, and the succubus taunts her for a second before barely dodging a bolt of light. She swiftly turns around and flees back in your direction with the angered angel in close pursuit, a golden spear in hand. Tail twirling around your leg, you shiver in anticipation.

Suddenly a sharp voice pierces your mind. It takes a second before you realize it's simply the angel shrieking at her prey.
"Burn in Hell, Demon! Your master will have to scoop your ashes off of his doorstep!"
As she finishes her sentence, another arc of light blasts off of her spear, piercing Selena mid-flight. The succubus writhes in pain for a moment, before dissolving into ashes. Luckily, the angel followed her close enough for the trap to work.
You look at Raven.
"Hurry! Complete the binding ritual!"

The demons quickly form a circle, and begin chanting.
Dies irae, dies illa
Solvet Saeclum in favilla
Teste Satan cum sibylla.
Quantos tremor est futurus
Quando Vindex est venturus
Cuncta stricte discussurus.
Dies irae, dies illa!
The angel notices about halfway through, but too late. The ritual had already latched onto her light, and was dragging her towards the demonic circle. She was pulled by long tendrils of shadow, screaming and kicking, hurling curses all the way to the center of the circle, where one of the tendrils ripped the spear from her arm and flung it off the rooftop.
Over the linked arms of your comrades, you sneer at this servant of god.
"Welcome, Little Bird. We hope you enjoy our hospitality."

"I will not bow to worms such as you! You roll around in your Sin, wreaking havoc of the orderly world around you! There can be no recourse for any of you!"

"Believe me, we request no recourse. Now please, sit down, relax. We want to know why you are here, and how God has already noticed our little "Insurrection"." The shadow tendrils proceed to rip off her white robes and pull her flat on her back. You look over the winged being curiously, taking in her small breasts and spotless but plain body.

You now have two choices. Destroy this pitiful angel, or attempt to corrupt her? Neither option will be easy, but, while extremely challenging, corrupting her could reveal important intel. Then again, you could always just **** the information out of her before destroying her.
