we have to think about evil just as we have to make snow angels and people and monsters as we are still children all through life facing some terrible criminals embedded in a system that is tantamount to terror in it's very essence. it is a terrorism against nature and life, which includes us. so we have to ponder evil as we mold snow when it's malleable. we have to make evil malleable or it will consume us and destroy our natures. 
walking this morning seeing a car angrily race around a bus in an intersection without pausing for living i thought how evil is not a phenomenon that can be isolated by law or absent morality, it's an evil system, that's why people behave evilly, they are simply products of the system without refection or imagination to connect them with the larger world, and the vanishing world of nature. evil is systemic and you can't get rid of the monster of the system without finally getting rid of the system and starting again, which seems nigh on impossible leading to despair in the stifling exhaust of evil. the monster is the system, he is the monster of the system he is the cancer and the host. he will perish too but the system will continue to consume. we have to make evil malleable. we have to simply make something of ourselves.
