After reaching this point I believe we can rest assured, even if Magari is still on death row.
The way this mangaka deals with drama and character developments, I imagine that even if Magari ends this her death will not be an event in this story. She will just live and eventually die like any other people, no fuss about it, even if the life span ends being a little shorter than average.
If, if this happens, because for everything we know she is cured and 100% healthy.
