Weevil...evil

Is evil a thought, a deed, an act, a moment, an emotion or inaction
Is it in the mind, heart, body, soul, word or in your fingertips...
Is it happiness, sadness, anger, disappointment or dissent
Is it sensile, tactile, ductile, virile...
Is it a smell, a worm, a bug, a weevil
black, blue, red or indigo...
If evil lives...
How do we know it?
