Here are the questions I would ask instead.
1) Will there be an ultimate judgment and final justice?
2) Does that make life on this earth more or less important?
I don't believe in an afterlife. Some would argue that makes this life meaningless since what you do here doesn't determine where you'll spend the rest of eternity. I would say that the existence of an afterlife allows us to ignore injustices by believing that all will be settled in the end.
If, however, there is no "final justice" then we need to make things right now. This life is even MORE precious and things like abortion and murder are even more horrendous if this life is all there is.
