A moral example becomes misleading when its clarity depends on removing the people involved.

Moral examples get their sharpness by removing detail, and the detail removed is usually the people. Strip away the histories, the relationships, the reasons someone is where they are, and a clean answer appears; put them back and the clarity dissolves, which suggests the clarity belonged to the simplification. Neat cases teach neat thinking rather than good judgement.

Use the examples, and then do the harder second step of restoring what was taken out. Ask what you would need to know if these were people you had to face afterwards. Real decisions arrive with all the detail attached, and practice that only ever happens in the stripped-down version does not transfer well.
