We are supposed to be "bodily" resurrected now, and live as if in a perfected spiritual state (Eccl. 12:7). Thats what mikvah, sacrifice (killing off animal soul by substitution as if starting over) etc. were all about.
Not a form of god appeasement or cause and effect.
Ultimately on physically dead people are in a perfected state (I don't believe in bodiless souls, you don't need to add to this.
