Cinderella endures mistreatment from her stepmother and stepsisters without retaliating, and when her fortune reverses she forgives them and secures their advantageous marriages rather than taking revenge. The tale pairs undeserved suffering with a final elevation that comes through outside intervention plus the sufferer's maintained graciousness.
Little Red Riding Hood's straying from the path and her trust of a stranger lead directly to her being devoured, presenting a child's small lapse in caution as catastrophic rather than correctable. Viewed this way, warnings to the young are encoded as narratives where curiosity and friendliness toward charming strangers carry fatal stakes.
In Sleeping Beauty a fairy cannot undo the death-curse laid on the princess but can only soften it, converting death into a hundred-year sleep that eventually ends. The mechanism is that harm already set in motion gets mitigated and delayed rather than erased, with resolution arriving only after the full term is served.
