The point is to pray for a sinners repentance, not rejoice when he dies in his sins and is taken to hell. If I was this mans pastor, I would fear judgment day much more than he should. For the pastor's job is to Sheppard his flock. Tiller obviously was not very open to that.
I rejoice when my enemy dies.
Call me old school.
I only respect a fallen enemy that has earned it.
