Why does Scrooge like darkness?

The most obvious reason Scrooge likes the darkness is because it saves him money on having to buy candles, and Dickens spares no expense in letting the reader know that Scrooge is a miser, for he tells us that Scrooge is " a tight-fisted hand at the grindstone,. . . a squeezing, wrenching, grasping, scraping, clutching, covetous old sinner." All of these adjectives allude to Scrooge's relentless miserly love for money.

However, one could argue that Scrooge likes the darkness because darkness represents evil, and Scrooge is characterized as evil in "Stave I," for many times Dickens tells us that Scrooge "growls" his responses suggesting that he is some sort of creature; another example is found when Dickens describes a blind man's dog pulling his master into a doorway to avoid contact with Scrooge and wagging its tail as if to say that "no eye at all is better than an evil eye, dark master." The "evil eye" being Scrooge's.
