If you're willing to be the 
sole sacrifice, then...
Wenn du also das einzige Opfer sein willst,
Si estás dispuesta a sacrificarte,
 acabaré con todo esto.
Si estás dispuesta a sacrificarte,
 acabaré con todo esto.
Il suffit de ton unique sacrifice
pour que tout prenne fin.
Se desideri sacrificarti

Se você deseja ser o 
único sacrifício, então...
Ведь стоит тебе пожертвовать собой,
как всё закончится.
