Melkor and sacrifice

[Rawel]

I have a question. I just started a melkor worshiping AxeMaster but intend to destroy the ring and probably switch to Eru for end game. I was wondering what happens to sacrificed hitpoints/extra damage? Do they both stay as they were? Do the hitpoints stay but damage is taken away? Or are both taken away?
Thanks,
Rawel

ps.: playing tome 2.3.5
