I think about in the following terms:
1. There is an after life:
     a. You go to the good one: Great! Fear of death not necessary.
     b. You go to the bad one, and it's infinite: Not great, but before 'your' suffering is 1/1000000th of the way complete, 'you' will have achieved complete ego death and will be completely unable to recall that there was ever a world, a body, an entity named '[your name]'. In the complete homogeneity of suffering, there will be no suffering. Great! Fear of death not necessary.
     c. You go to the bad one, and it's finite: Not great, but even if it lasts 100000 earth-year-equivalents, it will be over infinitely sooner than eternity. Also see point 1.(b) about ego death. Great! Fear of death not necessary.
2. There is no afterlife: Your suffering is done. Great! Fear of death not necessary.
3. You are reincarnated: Great! Fear of death not necessary. Keep trying 'your' best.
