Bad credit means possibly being denied a loan or can result in being charged higher interest rates. This is because the amount of interest you pay is based on your level of risk and the current market rate. The worse your credit is, the higher your level of risk is and the higher your interest rates will be.
When the bank gives you a credit, you get more money. Based on that transaction, it would appear that credit = positive, when in fact the opposite is true. The reason why the bank calls it a credit is because it is a credit on the bank's books. They just reduced the amount of money in their account, and thus credit = negative. But because your account increased, it's actually a debit in your books. That's just one more way you can see that the bank is thinking about their own profit--not yours. It's positive because it increases the cash account.
