I feel that 'dark' is a very vague adjective. However, that's the overall theme of this arc and what the Commandments have been doing especially after killing Meliodas, immersing the realm in "darkness".

And the author uses the adjective himself, as Loki71 pointed out, in the kick-off chapter for the current "age"/"stage" the NnT universe is going through. Camelot is down, Lioness under attack, the Commandments have been wiping out entire communities all around the center-stage or slowly "draining" them out through the tributes/sacrifices they're taking for magic replenishment.
