How does the short story "Babylon Revisited" demonstrate the universal truth of sacrifice?

Here is one definition of
sacrifice:

. .
. the act of deliberately following a course of action that has a high risk or certainty
of suffering, personal loss or death (which could otherwise be avoided), in order to
achieve a perceived benefit for self or
others.

In "Babylon
Revisited," Charlie Wales is clearly a flawed man, but he is also a man who chooses
self-sacrifice at significant times in his life. Although he loves his daughter Honoria
deeply, Charlie gives up custody of the child, knowing that he cannot care for her and
that she will have a stable life in Paris with his wife's sister, Marion Peters, and her
husband.

After battling and apparently overcoming his
alcoholism, Charlie moves to Prague where he works responsibly and rebuilds the fortune
he had lost. He is safe in Prague, living a healthy life far removed from the excesses
of his old, decadent life in Paris. His love for Honoria, however, compels him to
sacrifice the safety of his new environment in Prague and return to Paris, the place
where old memories of his painful past await him. Charlie sacrifices peace, as well, by
returning to Paris to regain custody of Honoria. Familiar sights and sounds remind him
of the many ways he had destroyed his life; he is haunted by dreams of Helen, his dead
wife. Returning to Paris exposes Charlie to great emotional pain and threatens to wreck
his sobriety; he knows the dangers to his hard won and tenuous well being, but he goes.
He risks all for love of Honoria.

In facing Marion Peters
again, Charlie sacrifices his pride in order to regain his daughter. He appears humble
before her, making only weak efforts to defend himself against her contempt and
disparaging remarks. When Marion decides that she will not return Honoria to him at that
time, Charlie accepts her decision. Fighting Marion for custody of his daughter would
surely have disrupted Honoria's life and destroyed her security. Charlie chooses instead
to leave his daughter behind, for a while longer. He will endure the separation for her
benefit. Charlie sacrifices what is most dear to him out of his love for his
daughter.
