Gluttony

Gluttony is the sin of uncontrolled appetite. This is a dark sin because they worship food instead of God, and this is reciprocated by the rain, which belies the jolly nature of gluttons and gives them dark temperaments.

Gluttony is a sin which involves one person, and it is more of a selfish sin, but the gluttonous are alone because they always ate alone even the day they eat themselves.
