(They have traded their souls for power, which is what they all crave)
Exactly.
Matthew 19:22-24
21st Century King James Version
22 But when the young man heard that saying, he went away sorrowful, for he had great possessions.
23 Then said Jesus unto His disciples, “Verily I say unto you, that a rich man shall hardly enter into the Kingdom of Heaven.
24 And again I say unto you, it is easier for a camel to go through the eye of a needle, than for a rich man to enter into the Kingdom of God.”
