Through rose-colored glasses

Here's the story of Rachav as told in last week's haftarah.

Summary:  Rachav was a prostitute who chose to help her city's enemies in order to save herself and her entire family.

Here's the story of Rachav as told in midrash (rabbinic legend).

Summary:  Rachav was a prostitute who was so impressed by what HaShem had done for the Israelites that she converted to Judaism, married Yehushua Bin Nun (Joshua), and become the ancestor of numerous prophets and Kohanim/Priests.  [For the record, no, I don't believe any of this, but I give our ancient sages credit for having good imaginations and good intentions.]

Judaism tradition seems to alternate between showing our heroes with all their faults and turning our heroes into saints.
