Just a watchful eye to realize the impulse to violence that acts as a destructive force in mankind and in society from all ages. Violating and corrupting seem to be constant traits in the social life, from their most expressive aspects to the most subtle ones. This paper enters into Genesis text, Gn 4,1-16, seeking to understand Cain s drama in which he cannot live fraternity with his brother. Cain is present throughout generations and in popular belief, as an archetypal presence of the conflict of the human being with his equal. This character brings in himself the symbolism of the violent forces and of its consequences when he allows these forces dominate over the actions. Therefore, his image permeates time in his fate, wandering vagrant in every person confronted with its limits and impulses. Getting to know the Biblical accounts and their meanings allows deepen the human history and their relations with the sacred and the profane. Seek for the significant roots of these Biblical accounts is to contribute with a meaningful channel capable of bringing, to the contemporary s man, the sacred wisdom of the ancient Israel, on its paradigms and paradoxes. Thereby, the investigation aim is to realize what are the driving forces that cause that violent reaction in Cain s character, elucidating, thus, aspects of the violence present in the human being.
