This writing investigates what the strength of change has on causing existent death on one's life through a method that consists of one dealing with oneself and also emphasizes the role of existential philosophy, which contributes to help one overcome the fear of death. Previously, traditional religions or philosophy fulfilled the consistent role of overcoming the fear of death; now, modern medical science has taken charge over that role. However, modern medical science may supply prescriptions to temporarily forget the fear of death, it is unable to offer a fundamental alternative way of recovering the fear of death. If anything, that fundamental alternative can be found in philosophy because death is an opportunity that makes it possible for the authentic existence of humans and insists the 'humanization of death' to be a fundamental and essential element of life; moreover, instead of an existential human being becoming anxious or in vain when encountering death under any circumstances, one goes through self awakening through death in order to go back to one's original self and avoid the apprehension of death. Of course existential philosophers debate about death from different perspectives with one another, they adhere to a common stance in which they 'independently' sublime the intrinsic understanding of death and related topics. The objective of this paper is to bear this point and seek what the meaning of genuine death and life is for the ones who live in the present from a multilateral theory of death in an existential philosophy perspective.
