what actions does scrooge take to make amends for the past?

Scrooge buys a prize turkey and sends it to Bob Cratchit's house. Scrooge dresses in his best clothing and walks in the crowds with a smile. He gives a great deal of money to the portly gentleman who had asked him for a charitable donation yesterday. Scrooge continues to walk through the city and happily talks with everyone he meets. He visits Fred's house and has a wonderful time at the party. The next morning, Scrooge gets to work early. When Cratchit comes in late, Scrooge pretends to reprimand him, then gives him a raise.

Scrooge continues his kindly ways, befriending everyone and becoming a second father to Tiny Tim, who does not die. He never sees the ghosts again, but he keeps the spirit of Christmas alive in his heart as well as anyone.
