“Burning “Lucille” was a gutpunch.”
He broke Lucille on the walker in the field and burning her in the fireplace was closure.
That was a symbolic funeral for his wife, Lucille.
Several times in the series he has mentioned that his one weakness was that he couldn’t put her down after she turned.
He hated himself for that weakness, which is why he turned hard, to deal with the buried pain.
Kinda surprised me that he did it, really.
