A conspiracy is a noble intent which needs to take ugly but necessary steps out of the public eye. Most people don’t act with pure malice. Most people shield themselves from truth and act true to themselves. So bankers can justify their huge bonuses and their immoral actions against humanity. Politicians can justify their corruption and society as a whole can give an almighty shrug.
When our authorities decide to arrest a trouble maker we don’t think of it as a conspiracy unless we are in some way with the trouble maker. We think the authorities are doing what they are supposed to. So when the priests and scribes plot Jesus downfall they’re merely trying to neutralise a possible terrorist. Unless of course you’re on the other side and see it as an extreme injustice.
Jesus on the other hand seems to lead a counter conspiracy. One that would reveal human conspiracy as pitiful attempts to hold on to power and reveal the naked broken God who takes on the fury of conspiracy and suffers with its victims.
