Mother Courage Fate

I feel like Mother courage is going overboard when she decides to call out her own childrens fate. That is basically asking for something bad to happen. Even though she decided thier fates to be Eilif would die for his bravery Swiss cheese will die because of his honesty and worst of all the daughter Kattrin was going to die because of her kindness -_____- NOW LETS BE HONEST HOW ABSURD DOES THIS SOUND? Thats like a kindergarden teacher saying to one of her students that by the time you are 18 you will either be in jail or dead like u just dint say things like that.
