Jackie's ending

The sexacapade with Ryan was only the first one of many. Jackie was now a permanent resident of the realm of lust of the archdemon Astaroth. The more sex she will have and the more her soul will be diminished. when nothing human will remain in her soul, she will become a newborn demon in the service of Astaroth.

Is it the end for Jackie or a new beginning?

Please let me know in the comment if I should explore this branch of becoming a demon in the service of Astaroth?

Should I do it in a separate branch or a whole new story?
