The gravitational redshift gets larger and larger as objects approach the event horizon. Photons coming from person B and from the rest of the universe are blueshifted. The tidal forces and the rain of high energy photons will be very bad for the person falling into the black hole. Tides Tidal forces are due to the difference in the gravitational force across an object. Near a black hole gravity changes very rapidly with distance.
Tides pull on the object and stretch it in the direction of the star.
BHs don't go around scooping up people and stars. Only if you get very close to one is there a problem. But we'd have a problem keeping warm.
