Little Red Riding Hood should not get an answer to that question. That's the point of "No One Is Alone": "Witches can be right, giants can be good, YOU decide what's right, YOU decide what's good." It's not "the authors decide what's right" or some sort of moral hierarchical power decides what's right. That's the beauty of INTO THE WOODS.
I call bologne on those people who say the tonal shift in the second act (in the show, no idea how Marshall handles it) doesn't work. It's one of the most genius ways to approach a second act, and INTO THE WOODS would not be INTO THE WOODS without that second act, just like SUNDAY IN THE PARK WITH GEORGE would not be what it is without that second act. To say that the second act of those shows don't work is to entirely miss the point of each piece, and to miss the genius of how Lapine and Sondheim brought postmodernism to the Broadway musical.
"Some people can thrive and bloom living life in a living room, that's perfect for some people of one hundred and five. But I at least gotta try, when I think of all the sights that I gotta see, all the places I gotta play, all the things that I gotta be at"
