worse and worse

Whenever I think the script can't get worse, it does! Amazing! WHY all the trouble with finding a replacement for a child that is supposed to be killed, if you're gonna kill the child ANYWAY?! There's no point in that! Only complications, efforts, million risks! Pure nonsense! If the father of the child don't agree to kill his own daughter, but let the accomplice find a replacement, then why the murderer pressumed he would obey her when she betrayed him and intentionally killed his daughter? I'm speechless how bad the script is!
