@TrueGoddessReincarnation I think this is just to show the audience that the army isn't a hive-mind of evil there to rape and pillage Tempest. There are people like that but there are those being killed who are just doing their jobs for their family and loved ones. This kind of sets the tone for why the system granted Remiru 'Merciless'.
Oof...really shows how none were spared, but it makes sense. I do like how the artist/author decided to include this snippet, really gives it more flavor
