Indulgence & Tarzan

[theoretical]

Perhaps FF changed the name to Indulgence simply because Tarzan is a trademarked name.

As for his original thinking to name the chest Tarzan, perhaps it came from the title of Tarzan’s Quest. From Wikipedia: “ As revealed in Tarzan's Quest, Tarzan, Jane, Tarzan's monkey friend Nkima, and their allies gained some of the Kavuru's pills that grant immortality to their consumer.”

Tarzan, rearrange the sounds and you get an-tzar, answer. Maybe it's the answer to the riddle of the poem.

I don't have any ideas on Indulgence unless it's literal and Forrest needs absolution for something.
