thanks God? Let yourself get revenge, your daughter is safe? Or thank you for being strong enough and working hard?
No, she was not thanking anyone, but Bill.
Why thank bill?
I think it's thanks to Bill for letting go and returning her daughter to her.
From the moment he knew Kiddo was taking revenge, Bill was able to stop her, but he didn't. Instead, he let Kiddo break his men one by one, because she deserved the revenge. When Kiddo stepped into Bill's house, Bill also had many opportunities to shoot her directly like Bud. He didn't, because he still loved Kiddo. But facing the blade of Kiddo's revenge, Bill knew her determination and he had to face it, so he didn't explain or ask for forgiveness, but instead followed her will and duel seriously to fulfill Kiddo's revenge. But is Bill's death really the result of kiddo's revenge? I think it was Bill's own choice, otherwise he would not reveal his whereabouts through his friends and give up his most powerful weapon. These kiddos knew everything in their hearts, just for the future of their daughter, and to give themselves an explanation, they had to make a break with Bill.
Before, Bill didn't know what would happen to him after shooting Kiddo. The reason why Kiddo cried in the end was because he didn't expect to kill Bill and find that he still loves him.
