How does Satan’s Diary develop the theme of Identity and Transformation?

Satan’s Diary by Leonid Andreyev develops Identity and Transformation across the chapters the companion marks for this theme.

Satan's transformation into a human named Henry Wondergood forces him to grapple with the limitations of human form, language, and logic, leading to a crisis of identity as he becomes a 'slave' to earthly existence.

Satan struggles with his new human form, feeling trapped and uncomfortable, as Wondergood's identity encroaches on his own.

Satan grapples with his new human identity, emotions, and memories of his past as Satan.
