It’s a bit of an absurd question. It’s certainly not the situation we face in the secret mission. Success doesn’t hinge on Lady Aleksandra’s murder. Khorobirit loses, with or without us. Nations rise and fall, with or without us.
I’m not accepting or rejecting anything. Killing a child is evil, and no sane person can refute that. It may be that you can justify the act to yourself through some ruthless calculus of what terrible events might occur if you don’t go through with it, and there are plenty of people who would agree with you. Royal Intelligence and Cazarosta among them. But don’t expect everyone to line up to shake your hand and pat you on the back because you shot a girl in the neck. A lot of people won’t be okay with it, and that’s their right. “The ends justify the means” isn’t an objective truth readily accepted by everyone.
We all need to justify the things we do if we want to be able to live with ourselves. “Whatever I’m able to take for myself, I deserve” sounds like your character’s justification. “Animals aren’t people, really” is how I justified the bacon sandwich I just ate. It’s the way we maintain internal consistency, which allows us to function without suffering a nervous breakdown.
No judgement here. Just sayin’.
