[Warcraft]Why did Arthas cull the population of Strathlome? Wouldn't the Scourge just bring back everyone as Undead anyway?

I get that Arthas went a bit loopy in his quest for vengeance/stopping the plague but unless he turned everyone into unusable red mush wouldn't it have been trivial for the Scourge to raise them back up? 

Also Strathlome did eventually end up in the hands of the Scourge, did Uther or Jaina ever comment on Arthas being kind of right about the spread of plague?

At the time, he didn't know that the scourge would eventually sweep over the land and start raising corpses. He just knew that eating the grain = death and zombies. And he also knew that Stratholme had been fully saturated with it, to the point of watching people eating bread made just that morning. He could not prevent their horrible fate, but he could prevent the zombies from spreading out of their town and into the rest of the kingdom. 

It was a lose-lose situation no matter which perspective you had. Jaina and Uther were blinded by their idealism, and would have eventually run into a brand new army on their literal doorstep because of their inaction. Arthas was blinded by his anger and desperation, and rushed headfirst into wholesale slaughter without thinking of any alternatives. (not that there were any. aside from powerful magic they did not possess) 

Jaina has more recently expressed severe regret over the way she handled the situation. But mostly because she "wasn't strong enough" to pull Arthas away from his dark path. And while she hasn't explicitly said that he was right about Sratholme, she has been frequently compared to him when she goes into a dark mindset and tries killing mass numbers of Horde.
