What is the meaning of death in the final scene?

In the end, Patricia betrays Michel, and it seems that the faith he put in her was blind, colored by the ardor of romantic love. As abruptly as she decides to love him, Patricia decides to betray him, anxiously taking a seat at a nearby bar and calling the authorities. Her betrayal is all the more heart-wrenching because it occurs just before he tells her he wants to leave the country with her. Just as he commits more fully to their affair, she gives him up. The game of push and pull between them, the hot-and-cold nature of their affair, ends in a particularly tragic way. The violent edge that they dance along (but never cross) in their affair is breached when Patricia makes the call and Michel is doomed to death.
