What does the Bible say about the darkness of Judas's betrayal?

In John 13:30, it is stated that after receiving the sop, Judas went out immediately, and it was night. This signifies not only the physical darkness but also the spiritual darkness enveloping Judas at the moment of betrayal. This act was not merely a transaction for thirty pieces of silver but a profound spiritual rebellion against the light of the world, Jesus Christ. Judas's actions illustrate the ultimate consequence of turning away from God—separation from the light and entering into darkness, a fitting representation of a heart influenced by Satan.
