I just read the section about Tartarus and saw that blood sacrifice is listed as something that would warrant this punishment (rightfully so). What about situations such as being drafted into a war? Obviously murder is wrong too but are nuances taken into consideration?
Intention matters. It boils down to that, and there is a lot of nuance in being drafted to a war. For example, no guarantee of experiencing combat. And, some individuals need to undergo military experience to grow and evolve as human beings. More about intentions: It is easy to look from an earthly perspective at the situations of our lives and our reactions to these events by us. But Gods do not judge based on a superficial level. When they judge, they take everything into consideration, and that means everything you can think of and more. So when a man kills another, as the trajectory has already been set, it must happen. It comes down to the cosmic dance unfolding.
For example, a man kills another man that murdered his child
That is justice. Unfortunately, in the modern world, justice has been perverted to great lengths.
