So I'm currently reading this book, in which a species of aliens are convinced (and have proof) that they are reincarnated after death. Due to this, they are mostly unafraid of death in combat and warfare, and suicidal missions are often considered 'worthwhile' if effective. Moreso, they consider the fact that other species (humans) that do NOT reincarnate to be lesser creatures (effectively 'smart animals') because of this. However, the thought of non-reincarnation terrifies them, as it is effectively the closest thing to hell they have.
A particular section piqued a question for me, in which a person went on a suicide run in combat with the thought that he would 'be remade some time later, in a better time'.
This is not a discussion of if reincarnation exists or religion. My question is this, assuming reincarnation were provably true, and after death you were put into a 'queue' to be remade as a person, not anything else (and theoretically have some access to past lives/memories), would suicide rates be higher with society as it is now? Do you think people would be much more likely to off themselves with the plan to just 'wait for something better'?
