Responsibility and Cain's freedom
Responsibility > Entrusted to man
Cain is free in the face of sin; he can master it and so he is asked to.
Then, when asked about the fate of Abel, Cain lies and eludes with arrogance.
Thus, ideologies mask indifference and crimes towards the person: ignoring them and rejecting the responsibility for the other.
Moral indeterminacy mitigates subjective responsibility because of selfishness or efficiency; it is hedonistic and irresponsible to conceive of a freedom that rejects obstacles to personality and exonerates from the Law of God.
“What have you done?” (Gen 4:10) calls for gathering the seriousness of gestures, motivations and consequences against life, often because of demands of recognition and protection of so-called new freedoms and rights.
