CMV: Uther was in the wrong when he left Arthas before the culling of Stratholme.

By abandoning Arthas at Stratholme, Uther would have allowed the undead Scourge to spread even further and take more lives. By the time Arthas had arrived he was simply doing damage control and minimizing the body count. There was no good way to know who would have eaten the infected grain and would turn. Everyone in the city could have been quarantined, but that would have left an undead legion for Mal'ganis to use against Lordaeron. By killing everyone in the city, he slowed the spread of the plague. Arthas' mistake was not in the culling of Stratholme, but in following Mal'ganis to Northrend and taking Frostmorne.

I think you're missing the point. The purpose of this was to demonstrate to us Arthas slipping further into darkness. While logically it made sense, where would it stop? Would Arthas have marched through the country side slaughtering every town he came across if Mal'ganis made him believe there was infected grain? Uther left because he saw that Arthas was out of control and beyond help, no longer a Paladin.
