Are these people even conscious of what they are doing?
Zombies might be a compliment. That woman looks like she is demon-possessed.
The cure for these idiots is laughter to drown them out. The power of darkness cannot overcome the light. The being they worship was known as Lucifer the light bringer. He now brings the darkness and calls it light.
Come out of slavery my people, Christ begs for them to come to him. Yet they reject it and crave the darkness.
This is sad, but we are not to pray for them. Walk a straight path, set an example but stay away from these condemned, they can only destroy the light within you if they could.
