It is so much easier to deal with the dead than with the living. The dead are out of the way, merely characters from stories about the past, never again unreadable, no misunderstandings possible, the pain coming from them stable and manageable. nor do you have to explain yourself to them, to justify the fact of your life.
There are studies that have shown that we make decisions, ethical and otherwise, based on the way we imagine ourselves as characters in the stories of our lives. In other words, if we imagine ourselves brave or crazy or open, we're more likely to make decisions in a given situation based on how we imagine ourselves, whatever the facts may be.
There's something in psychology called the narrative paradigm, which essentially means that we think of our lives as stories in which we are the main characters.
