Pansychism seems to explain a lot of the hard questions. Even without a deeper understanding than 'there is a single conscious and you are a piece of it', simply thinking that way changes the understanding of life/death. You are unknowingly everyone. Punching a guy is on some level punching yourself. The afterlife is irrelevant, when you die you go on existing as the other 7 billion humans, plus animals, etc... This is why philosophers and neuroscientists alike a so excited about the idea and writing papers about it.
