[Doctor Strange] Why was Dr. Strange allowed to keep the eye of Agamotto after he was caught using it recklessly? From that point on in the film he never returns it to its place in the hall in Kamar-Taj. Wouldn’t possession of the eye fall to the sorcerer supreme if anyone? Not even she carries it.

The Ancient One put all her chips on Strange. She'd been waiting for him for years - she was fully aware of him and his activities at least as early as the first *Avengers* - and everything she did, like making him sit outside for a few hours before offering to teach him, was designed to groom him as her replacement.

The Ancient One was also smart enough to know what she didn't know. She trusted her instincts that Strange would be "the best of them," and if he decided that he needed the Eye, that was good enough for her. The rest of the Masters simply followed her lead.

Also, the Ancient One *did* carry the Eye when necessary; we see that when Professor Hulk visits her in *Endgame*. Being ready to use the Eye in the face of world-ending catastrophe is common practice, and Dormammu breaking into this reality certainly qualifies.
