In the Marvel Cinematic Universe, villains typically perish by the end of the movie, one way or another. Only a few break from that mold. Adrian Toomes, “The Vulture,” and Helmut Zemo are captured and imprisoned. In Ant-Man and the Wasp, the heroes realize that their antagonist, “Ghost,” is simply misunderstood, and they befriend her. Talos and the Skrulls turn out to be victims of the Kree, and they persuade Captain Marvel to fight (but not kill) the Kree leadership.
Notably, some of the surviving antagonists join the protagonists. Loki is a prominent example, of course, but another is so significant that people hardly remember he was ever on the wrong side: Winter Soldier.
