I enjoyed this but the ending was left up in the air, not entirely resolved

Are you thinking they should have both quit their jobs, and just worked normal jobs, and lived their lives without killing people? At least they got to stay together, neither one killed (that would be the ultimate end)

i actually really like the ending, normally there will be drama and conflicts i mean its already rare to see this happen! and in a evil vs good tropes so i'm happy it ended this way!
