"It seems you know literally nothing, despite your association with Liv Ivaldi. Well, ask her for the details. My point is that the world is safe only because Antarctica is a special case; if the same thing happened anywhere else, it would be the end of the world."

Lilly killed her heart to fulfill her duty. As commander of the White Guard, she would have been at the forefront of most of the executions of rogue Reapers. Men, women, probably even children. Anyone with Reaper blood had the potential to become a Reaper.
This meant that the chances of Lilly having to kill the same person twice were quite high. Once to end their human life, and a second time for their Reaper life. Being given such a task by David must have made her despise herself.
