The subject of birth and death in RP is interesting. To my knowledge most homins can be resurrected an infinite number of times (having an age of over 500 Jena years is common), however the sacrifice the ability to reproduce biologically. The only thing that I know which can intentionally kill a homin is goo infection, which would prevent higher powers from resurrecting them. An exception seems to be royal/imperial/other leadership families, who experience both death and birth. Possibly the reason they have taken their role is in part due to the miracle of birth making them seem blessed by the higher powers.
