How did Scrooge choose money over Fezziwig?

Scrooge initially disowns Fred, cutting him off without a penny, as he mainly blames Fred for the death in childbirth of his much loved sister Fan. Scrooge is more annoyed by Fred's marrying someone who herself has no money to her name. When the Ghost of Christmas Present takes Scrooge to Fan's bedside he sees himself begging for her life. She falls into a coma as Scrooge sits holding her hand. He glares at the baby as it cries and leaves the room. When he'd gone, Fan in a faint voice still speaks to Scrooge, begging him to take care of her son. Scrooge never knew of this and breaks down seeing the events. He knows he has let his sister down. In stave 5 Scrooge goes to Fred's home to beg forgiveness for his folly. Fred is of course delighted to see his old uncle and welcomes him to his home for Christmas Dinner.
