Was the discounting by the manager in Luke 16 a dishonest act?

Using Drash in Sensus Plenior:

   Scriptures from various sources are linked together by common theme, similar structure, or even as little as shared words and phrases.
   The various scriptures are taken as transparencies which overlay each other to produce one picture.
   The context of each overlay may be shared with another.
   The meaning of the compilation is discerned, using a Christological frame of reference.

Linked portions of scripture:

   The story of Jacob
   The prodigal son
   The shrewd manager

How they are linked:

   The actor takes what belongs to another.
   He spreads it around
   He is commended or rewarded.

Jacob took the inheritance and ran away. Upon his return he forfeits all by placing all his belongings ahead of him as gifts to dissipate Esau's anger before Jacob arrives. He is welcomed back.

The prodigal takes the inheritance before his father is dead. He spreads it all around until there is nothing. He is welcomed back and given more as a son.

The manager takes what belongs to his master, spreads it around, then is apparently commended for doing so by Jesus.

Interpretation by various voices of sensus plenior:

In the voice of the judge which asks for a moral determination:

All things that we have, no matter what the source, ultimately belong to God, and are not to enslave us in this world, but to be profligately spread around so that we return to the Father empty handed, as Christ gave all and was fully spent on the cross.

As such the merchant is not a human merchant who is being cheated, but represents God who owns all things. The shrewd merchant was freeing himself from the entrapment of the world system.

In the voice of the prophet which speaks of the life of Christ:

The Eternal Son of God left his high estate and emptied himself in the kenosis. He took his inheritance and "squandered it" dying alone on the cross. He was accepted back by the Father in resurrection.
