Stealing a Pen, Is There Any Abuse of Writing, Saving Everyone but Not Myself?

I want to read a book similar to "Tomb Raiders: Yin and Yang". As for the protagonist, he knows everyone's ending and tries his best to save them from the beginning. He is very strong and has a special bloodline. He doesn't care about himself. He uses his own blood very decisively. He saves everyone but not himself. It's a super sadistic novel.
