What effect is achieved through the use of the simile comparing grain elevators to Greek temples?

The best answer for this question would be the following:

The author had to define the effects of murder and mistrust in the novel, the holocombs were also important to the greeks stating that, travelers can see the beauty of the temples even before they arrive. And he also uses the simile in order to describe the ruins of the greek temples as they were destroyed beautifully and perfectly. This was a trigger for the townspeople to be scared and that they had to lock their doors. The effect of the murder of Clutter’s murder made the people more conscious to whom that they should trust.
