I mean, I’m Catholic, and thus I function on the basis of Catholic ideas of sin and redemption, where Catholic sin is just copy pasta of Jewish sin, but “atonement” is different between the two in many regards.
For me, “sins” are “missing the mark”. All actions should be oriented to A Good End, and the means themselves must also be Good. In Catholic Ethics, “ends justify the means” is not permissible; it is in fact condemned in the Church.
All actions (means + ends) must be judged upon their intent (of the individual) and what actually happened consequentially.
The effect is then judged upon 4 possible outcomes
- The action hits the mark = not a sin
- Falls short = sin
- Shoots over = sin
- Hits the wrong mark = sin
And then there are sins which are individual and sins which are communal.
Jaina and the Silver Covenant purging the Blood Elves were, for example, a communal sin.
The Orcs that participated in the fel-blood fueled invasion (which excludes Thrall among others, as he was a newborn baby later raised in slavery) is a communal sin.
Grommash atoned for his sin via personal sacrifice. He was redeemed.
Thrall (Go’el, Hebrew for Redeemer in the context of slavery) recognized the communal sin of the Orcs and settled in Durotan for the purpose of atonement as a people.
Garrosh had individual sins and he is mow atoning for them in Revendreth.
However, the sins of the fathers do not carry to the children, but their effects do (original sin gets into this topic), but that’s more complex harmatology/soteriology that isn’t necessary here.
Mortal sins, which are damnable and fundamentally damage the soul, in this case what would send you to the Maw, have 3 requisites:
- The sin is done with full knowledge of its sinful nature.
- The sin is done of your own perfect volition.
- The sin done is grave matter, a subject that God has explicitly condemned. Examples are murder, unjust or stolen wages, oppression of the poor (or peoples subjugated otherwise), and sexual violence.
World of Warcraft hasn’t specified what damns you.
However if it were a Catholic world, Arthas would not go to the Maw. His will was influenced by Zovaal, and thus had no perfect will. As an example. He’d go to Revendreth. Mortal sin, but not all 3 criteria.
Garithos would. Grave matter, full knowledge, and perfect will.
