Do you guys think maybe in her second life the crown prince manipulated her brother into killing her husband?

We know he was surprised she loathed him for it and that he's usually protective, even to the point of helping her potentially kill the Crown Prince in her first life despite how it'd cost him his life.

I am not buying he did a 180 and just found her being with a poor commoner gross or disgraceful and that was all it took. Just some thoughts..
