confuse the reader with another point of view.
show that Jekyll is a better writer than Lanyon.

Answer 1

add another perspective to the story.

Including Jekyll’s letter inside Lanyon’s account gives the reader direct access to Jekyll’s own voice and motives, complements Lanyon’s eyewitness report, and provides multiple viewpoints that deepen understanding rather than merely confusing or misleading.
