For Perfikot, dealing with the Evil God Sect was merely an incidental matter.
Even though her fundamental purpose in returning to Langton was indeed to solve the issues related to the Evil God Sect, and even perhaps to test whether Godslayer could be achieved, this was still not her ultimate goal.
Ultimately, from the very beginning, her aim was to save this world, to save humanity, and to allow more people to survive.
For this goal, she could abandon the Empire's homeland, renounce the Empire's colonies, relinquish the entire Old World, and even forsake everyone else except for those she saved.
She herself also set aside unnecessary sympathy and emotions for this goal, even forcing herself to become a strong-armed and cold-blooded ruler.
But throughout this journey, the actions she took have consistently served her grand mission of saving humanity.
