[Virgil]: "Now fraud, that eats away at every conscience,
is practice by a man against another
who trust in him, or one who has no trust.
This latter way seems only to cut off
the bond of love that nature forges; thus,
nestled within the second circle are:
hypocrisy and flattery, sorcerers,
and falsifiers, simony, and theft,
and barrators and panders and like trash.
But in the former way of fraud, not only
the love that nature forges is forgotten,
but added love that builds a special trust;
thus, in the tightest circle, where there is
the universe’s center, seat of Dis,
all traitors are consumed eternally." (Inf. XI, 52-66)
Because God with his infinite love created the universe, his love permeates everything, creating bonds of love between men and the world around them. Fraud, the most heinous type of sin, "cut[s] off / the bond of love that nature forges" because it falsifies man’s (supposedly loving) relationship to the material world around him. Whereas sinners of ordinary fraud like hypocrites, flatterers, and sorcerers generally betray the world around them, sinners of treacherous fraud first establish a particular bond of love with another person and then betray them, making the "special trust" between them "forgotten." Thus, fraud in a very real way is a negation of natural love.
