They say the devil you know is better than the devil you don’t know.
That’s mostly true, but only for cases where the person is not the actual Devil.
If you are working with a true Devil, then its better to take a chance on someone else.
A true Devil will destroy your business and your life.
He or she will guarantee your failure.
Swapping him or her for someone else at least gives you the possibility of success.
The devil you don’t know is better than the Devil you know
