As a living being, we have neural mechanisms, or modules, which instill a preference for positive stimuli and an aversion from negative stimuli. We then inherently label objects and beings as having a positive or negative valence. Since this labeling exists along a continuum, the extreme value of negative are called evil. Evil can be in you (as we often don't like to think but it is nevertheless true) or can be put onto you. We exist in a world of relationships. The only way to come to terms with the evil that exist within and around you is to liberate from these "conditions", maybe that's what we mean by death.
