Sin is a personal act
Sin
Sin is a personal act because the person is however free and inalienable; sin is a truth that cannot be disregarded, that would deny the person’s dignity and freedom, and therefore virtue and responsibility.
Even in real and anonymous situations with complex and not always identifiable causes, everyone must assume his or her responsibility.
Although a situation migth be neither good nor evil in itself, it is unlawful to soften sin by blaming evil on anonymous or vague entities: social sins are just accumulated sins of those who generate, exploit or promote iniquity, and of those who do not avoid, eliminate or limit the evil caused by their laziness, fear, conspiracy of silence, secret complicity, indifference or supposed impossibility to change.
