Yes, "The Warrior's Sword" intentionally questions the Doctor's morality. It shows you how far-gone this thirteenth incarnation is; he does things past Doctors wouldn't dare do. This can be derived from the fact that for many people, 13 is an unlucky number, hence the Thirteenth Doctor would be "faulty."

"The Queen's Mirror" has to do with people's fear of death. The world of Perfection worships beauty and is meant to play off of the Thirteenth Doctor's own vanity; people become obsessed with appearances in the first place because they wish to look and be young as to avoid death.
