Make sure that you are familiar with what access has been granted to that role or what that permission enables a user to do. If the user does not need to do sysadmin tasks the user should not be added to the sysadmin group. The same goes for the database-level roles if they only need to select data from a table the db_datareader should be sufficient. Not every user needs to be at the db_owner permission level. If a user is granted permissions beyond the scope of their specific need this principle has been violated.

Users Users are database-level principals that are created in order to access resources within a database. Database Users are typically mapped to a login certificate or asymmetric key. After you have created a login to SQL Server you create a database user in order to provide permission to a database and the objects contained within. In order to more easily tie users back to logins it is recommended that the Log-in and User names match. To aid in managing the organization of users permissions users can be added to any one or more of the available database roles or to new roles that you create.
