Ti-Jean & His Brothers

In the play Ti-Jean and His Brothers, there appears to be more than one devil. The devil is actually three people in one (Old Man or Papa Bois, Planter, Devil). There is also a soul Bolom (the Devil's angel), who goes to the residence of Ti-Jean and his family (pg.720 Prologue).
  The Devil wishes to acquire Mother's three son's, so he may feel human,"He is dying to be human" (pg.721 Prologue) says the Devil through Bolom..... the devil proposes a challenge for Ti-Jean and his brothers...... If anyone human can make him feel anger, rage, and human weakness, He will reward them... If your sons fail to give him these feelings their flesh shall be eaten, but whichever was brave enough they shall inherit the wealth of my prince and once they are dead I too shall feel life!" (Bolom pg721 Prologue).
