Clearly if he was a ghost he was dead, since ghosts aren't souls. However if his soul was wandering around, he wasn't dead. To the best of my knowledge in Cristian mythology only one man has been raised from the dead.
According to Wikipedia there are seven cardinal sins and suicide isn't one of them. Suicide is a mortal sin and condemns you to hell. Colin appears to be in purgatory.
good point on the difference between cardinal (sins that lead to other sins) & mortal sins.
Somehow I'm under the impression that ghost & spirit are interchangeable in Dresdenverse, remnants or echo of lost souls wandering in the world because they couldn't move on, while soul is, well what Uriel said
I was told that they have modified that doctrine a bit, depending on whether or not the person was mentally ill or not at the time. Captain Jack is in sort of a purgatory, neither Heaven or Hell, perhaps the only choice he has is whether or not he wants to earn a ticket to Heaven by working for Uriel.
yeah i took a quick peek on the precise definition from catholic cathecism, based on morriswalters correction
In Roman Catholic moral theology, a mortal sin requires that all of the following conditions are met:
- Its subject matter must be grave. (The term "grave sin" is used at times to indicate grave matter, and at times to indicate mortal sin. But it always remains true that the following two conditions are requisite for mortal sin.)
- It must be committed with full knowledge (and awareness) of the sinful action and the gravity of the offense.
- It must be committed with deliberate and complete consent.
so the 2nd point determines whether the act of sin committed is grave enough to be mortal or venial sin
As for Collin, I think he took the job under Uriel either because like Harry he needed to know what happened to him that led to his death, then decided that working for Uriel aligns/serves his ideals/purpose of vocation such as justice & family, or Uriel offered him the job because he was already closer to supernatural world than other humans when he worked in Special Division. Meaning he was righteous enough as a person to earn Uriel's respect
