The seven deadly sins, also known as the deadly vices or cardinal sins, is a grouping and categorization of human faults that, in addition to being contrary to Christian teachings based on the chosen object, the end sought or the intention and the The circumstances of the action or omission are committed repeatedly, repetitively or habitually, obscuring the conscience and distorting the concrete assessment of human acts (according to the Catechism of the Catholic Church, 1865, 1866 and 1750).
At the beginning of Christianity, all the religious writers - Cyprian of Carthage, John Cassian, Columban of Luxeuil, Alcuin of York - listed eight deadly sins. The number seven was given by Pope Gregory the Great and was kept by most theologians of the Middle Ages.
The term "capital" does not refer to the magnitude of the sin but to the fact that it gives rise to many other sins, according to Saint Thomas Aquinas
lust

pride
envy
avarice
