My only takeaway from this parable is, that landowner is out of his fucking mind for not evicting the tenants and turning them in to the police for murdering his servants the first time it happened, and then for sending more servants and his son to certain death.
Also, unless the son just happened to be carrying his entire inheritance on him, how the ever-loving fuck do the tenants expect to take it from him?
And finally, how does this story even begin to suggest that God didn't know Jesus would be killed? It reads like the exact opposite. This is textbook foreshadowing if I ever saw it.
