To whom could montresor be talking, fifty years after the murder, and for what reasons?

Nobody truly knows who Montresor is conversing with in the story. We can just figure with the clues from the lines that he is conversing with a pastor or a religious authority. Montresor is clearly admitting his wrongdoing of such huge numbers of years back, and it gives the idea this isn't the first occasion when he is admitting a similar thing. He is retelling, with some enjoyment, the points of interest of his murder of Fortunato. He goes into profound insights about the wrongdoing.
