+As usual, the Yudkowsky of 2009 has me covered. In his short story ["The Sword of Good"](https://www.yudkowsky.net/other/fiction/the-sword-of-good), our protagonist Hirou wonders why the powerful wizard Dolf lets other party members risk themselves fighting, when Dolf could have protected them:
+
+> _Because Dolf was more important, and if he exposed himself to all the risk every time, he might eventually be injured_, Hirou's logical mind completed the thought. _Lower risk, but higher stakes. Cold but necessary–_
+>
+> _But would you_, said another part of his mind, _would you, Hirou, let your friends walk before you and fight, and occasionally die, if you_ knew _that you yourself were stronger and able to protect them? Would you be able to stop yourself from stepping in front?_
+>
+> _Perhaps_, replied the cold logic. _If the world were at stake._
