Since that's the case, if the Demon King truly wishes for death, then she must create an environment suitable for the Hero's growth.
So, what environment is most suitable for growth?
Isn't it battle and war?
"Once a war breaks out, the Divine Race will inevitably assist the Hero in growing and training them to succeed."
"Once a war breaks out, the Hero can continuously grow stronger bit by bit through battles and slaying enemies."
"Of course, once the Demon King actively starts a war, she will become the evil in the eyes of the world, attracting the Hero's hostility and even hatred, making the Hero truly target her and vow to slay her."
"The First Generation Brave serves as an example, showing that only through opposition can accidents be avoided."
If the Demon King does nothing and only nurtures the Hero, even if the Hero becomes stronger, whether they will want to kill her is another matter.
