It has often led him to be liberal and generous, to give his money freely, to display hospitality, to assist his tenants, and relieve the poor. Family pride, and filial pride – for he is very proud of what his father was – have done this. Not to appear to disgrace his family, to degenerate from the popular qualities, or lose the influence of the Pemberley House, is a powerful motive. He has also brotherly pride, which, with some brotherly affection, makes him a very kind and careful guardian of his sister, and you will hear him generally cried up as the most attentive and best of brothers.

– Jane Austen

Pride and Prejudice, Chapter 16. George Wickham does have some good things to say to Elizabeth about Mr. Darcy, particularly regarding his family pride. He is proud of his father, kind and caring to his sister Georgiana and would not do anything to disgrace his family or injure the reputation of Pemberley House. What a shame that Wickham doesn’t have similar good qualities.
