Fred, Scrooge's nephew, and Bob Cratchit, his clerk, both treat him well even though he is a horribly miserable person. Fred continues to visit him, wish him Merry Christmas, and invite him to dinner. Bob has to obey him, of course, but he also makes genial overtures of friendship and toasts his health at Christmas even though Scrooge is not there to hear it.
The name of Scrooge has become a buzz word for a miserly, unsympathetic and cruel person. In short, he is a despicable person who is only concerned with the acquisition of wealth; he has no heart for anyone, no altruistic characteristics whatsoever. He generates no warmth; therefore, when others encounter him, they act negatively, as well.
Basically, people's behavior towards Scrooge is based on his behavior towards them. When Scrooge treats people in a cold and distant way, they reciprocate. When he finally starts to treat them nicely, they do the same to him.
So, if you are trying to say it very briefly, you should say that the reason for people's behavior is Scrooge's own behavior.
For most of the story, Scrooge is not a very likable character. He has no patience or sympathy for any problems that someone else might be experiencing, demands a great deal of others with minimal recognition or compensation given in return, and actively repels any attempts to make personal connections. As a result of all these characteristics, most other characters choose to avoid Scrooge whenever possible. His nephew persists in trying to reach out to the old man because he finds it a challenge and because he feels sorry for his uncle, but he doesn't really expect to succeed in his efforts. Obviously, during Scrooge's insights into his past, present and future in the company of the three Christmas spirits, people relate to Scrooge differently - and, in the end, Scrooge is able to take the lessons learned during those encounters and apply them to his real-time life. People's behavior toward Scrooge changes when his conduct toward them is transformed.
