I understand that you want to make a story/universe with worlds and characters from different movies, animes, mangas, etc. BUT! Saying that these Astartes do not want to eliminate civilians or in any case eliminate a group of Xenos is AN INSULT TO THE WARHAMMER UNIVERSE, apparently you are forgetting certain important things about that universe. I would recommend you re-read a story before making a WARHAMMER Fan-Fic...... At least rewrite the chapter to make the Fan-Fic more bearable.
