It is best if you accept the meaning that the word debit has had for 500 years: a debit is an amount entered on the left-side of an account . Don't add "good" or "bad" or "add" or "subtract" or other meanings.
If you associate the word "good" with debits, you will have a problem when it comes to expenses . After all, expenses have debit balances . Since expenses will reduce a company's profits, they are not good.
Lots of people have tried to make debit mean something more than left side . It never works. That's why after 500 years we are still using the unusual word debit .
