Leos Klein was never a religious man.
In his past life, he was an atheist and remained one up until the day of his death in Phobos. But he knew of faith, understood their significance to others and knew what they preached and represented. He knew of sins and virtues, of afterlives being dependent on how good or bad of a person you were in life. And he knew of reincarnation, of the soul transmigrating across time and space to be reborn as someone else.
So when he said he hoped that death would bring him to a better place in his last moments, he hadn't expected this.
