And they struck with blindness the men who were at the entrance of the house, both small and great, so that they wore themselves out groping for the door.
Genesis 19:11

The Sodomites had been struck blind, but kept trying to assault Lot and his guests. Typical of people who are determined to act wickedly. They are driven by their demonic masters to destroy themselves in flailing against the intrepid power of YHWH and are seldom swayed by any reasoned argument.

This is one of the reasons we know that Good wins in the end. Evil always destroys itself in time.
