Who was in charge of judging one soul after death to decide if they would enjoy each other life

All nine of these aspects were part of one's earthly existence and, at death, the Akh (with the Sahu and Sechem) appeared before Osiris in the Hall of Truth and in the presence of the Forty-Two Judges to have one's heart (Ab) weighed in the balance on a golden scale against the white feather of truth.

The ancient Egyptians recognized that when the soul first awoke in the afterlife it would be disoriented and might not remember its life on earth, its death, or what it was to do next. In order to help the soul continue on its journey, artists and scribes would create paintings and text related to one's life on the walls of one's tomb (now known as the Pyramid Texts) which then developed into the Coffin Texts and the famous Egyptian Book of the Dead

the two major parties acting together and cooperating when making decisions is bipartisan

the answer is selfishly. hope this !
