Terrible. Even if they don't care about her, what about her children? My guess is this is a political terrorism move to keep the people in line. The Sudanese government will play it for all it's worth and still hang her. Thus, the people will be in fear and manageable.
In Iran, they have just a few hanging offenses, but two of them are super broad. You can swing for anything that can be construed as an offense against Islam or treason. And, judges can decide just about anything qualifies as one or the other. I expect Sudan to go the same route.
