Logan is someone who fears love because whomever he loves dies or gets injured.
Hes in this horrible catch-22.
If he allows himself to feel affection, in a way he curses the person.
The couplet was People hurt me and I hurt people.
Laura grew up incarcerated and treated as an object, so her nightmares are ones of abuse.
He feels haunted by the violence of his 200-year life.
The violence he fear is not what anyone does to him, but actually what he does to others.
That was the seedling of the scene.
What the scene started to be about was a chance to address this bullet.
Its just word salad.
He catches himself, looking at the purity of his daughter, and tells her the straight truth.
Scott Frank and I were literally trading pages back and forth.
I ended the scene on I hurt people too.'
Then Scott wrote, Youre going to have to learn to live with that.'
Then Scott, literally as the voice of Logan, added, All the same.
This scene becomes about what the whole movie is about: violence good or bad scars the practitioner.
