One of my favorite WC3 missions was the Cull of Stratholme because it suddenly presented us with a moral quandary that had no easy answer.
Arthas realized that Stratholme had already been largely infected by the plagued grain and, in a moment that defined his character forever more, decided to conduct a callous purge of the entire city to include even the living. Uther, horrified at such a suggestion, refused to commit to what he saw as genocide and tried to convince Arthas to look for another solution. His mind made up however, Arthas ordered Uther to purge the city to which he refused. Outraged, Arthas called them traitors and disbanded the Silver Hand before going on to purge the city with those of his forces that stood by him.
Now from a moral standpoint, yes, what Arthas did was wrong because he killed innocent men, women, and even children, some of whom may not have been infected. But I submit the following question: did he actually have any other choice?
No, he didn’t. Let me explain why…
First, he simply didn’t have the forces much less the resources to quarantine such a large city. As WC3 and WoW showed us, it essentially boiled down to smaller forces moving from section to section as quickly as they could.
Had they decided to attempt to quarantine the entrance, it wouldn’t have been long before a flood of refugees they had no idea were infected or not started streaming out of the city en masse in a desperate attempt to get away from the undead howling at their heels.
And as his previous experience with the infected in Stranbrade, he knew it would not take long for them to turn and begin wreaking havoc. And with the sheer number of people in the city of Stratholme, it could turn into a veritable army all on its own and present a dire threat to the rest of Lordaeron were it to escape.
And without the numbers or time to process them, it would have quickly devolved into absolute chaos as fear of their lives would push the refugees to attack his forces in sheer desperation, weakening them to the breaking point and leaving them vulnerable when the Scourge showed up close behind them.
At this point, the quarantine would quickly fall apart and the infected would start streaming in all directions along with the Scourge, making the attempt far more damaging to Lordaeron than his original plan.
And secondly, Mal’ganis was in Stratholme. Granted, Uther very well could not have known this. However, this is critical as Mal’ganis was greatly speeding up the process of infection and conversion of Scourge within the city.
Left unchecked, he would have quickly turned almost the entire city before turning them against the now horrifically outnumbered defenders who would have been literally swamped under waves of Scourge. And afterwards, they would have quickly spread across Lordaeron as an ever growing mass that might have become unstoppable.
So in conclusion, while I believe Arthas’ decision was morally wrong, it was in fact the best choice he had from the very few available to him.
Deep down, I think Uther and Jaina knew it as well but they lacked the will to take such an unpalatable step. There was simply not enough time to gather reinforcements or realistically quarantine the city. To me, this was Arthas’ only option.
Terrible? Yes. Callous? Of course. Necessary? Absolutely.
Arthas’ only mistake in this regard was in letting his anger and arrogance get the better of him and drive away those who could and should have helped him. Had he calmed himself and explained the stark reality of the situation to the two of them, I think he could have reluctantly convinced them that this was a terrible but necessary action.
There was just no way to save the citizens of Stratholme, and this was really the only merciful end for them. Even if they were not initially infected, Mal’ganis would absolutely have made sure of it.
