Adding a repository for no reason is not a good thing to do but it is your system and you can do as you wish.

Did you have a specific problem with a package that caused you to run fix broken packages ?
There may be circumstances in which fix broken packages might need to look at repositories but adding an invalid repository is a problem. If we can reproduce what you did it would help.
