To "put an end to [something/someone]" means to cause someone or something to stop or to prevent something from continuing. Here, she means that she'll stop them from getting the good ending and result they want. Ex: I'm going to put an end to this misbehavior by contacting the kids' parents. Ex: They came up with a solution to put an end to the injustice.
