Answer:
a. death initiator
Explanation:
According to Edwin Shneidman, self-murder is defined as an action in the individual involved cause his own death. In other words, it is an intentional, direct and conscious effort of an individual to end his / her life.
Shneidman however, grouped self-murders into four, of which they are:
1. Death Initiators: those that want the death to come quickly because, they believe they cannot survive death at that moment, either due to health or accident.
2. Death seekers: these set of people wish to end their life, and not necessarily because of health issues. It may be due to other reasons e.g poverty.
3. Death darers: this set of people tends to fancy the idea of ending their lives themselves.
4. Death ignorers: this group of people believe in another life after ending their lives themselves, often times, they want to end their lives to go have a better life in afterlife.
Therefore, Shneidman would term Ernest Hemingway as a Death Initiator, because he believed that, his death is imminent regardless, due to his failing health. So he ended his life sooner.
