I need to understand the relationship between jack and edith.
Cant understand it even though i watch the movie in the circus tent
There isn't much not to understand. The movie in Queensland is fairly straightforward.
Jack is an individual who was thrown into the Mental Ward and had a boiling hatred towards women.
There, he met Edith Liddell by listening to her voice beyond the walls of his room in the Mental Ward.
Slowly but surely, Jack grew to like her
and understood that he didn't hate all women. He wanted to do something good for her; he wanted to take her out of the Mental Ward and show her the good parts of the outside world.
And the rest is obvious enough. Jack eventually escapes the Mental Ward, Edith turns into a demonbeast at some point afterward, Grimm comes around and meets Jack, and sometime later kills him.
EDIT: I made a mistake here. Jack always hated whores and only them from the start. My bad, I misinterpreted what I read in the movie at Queensland.
