In Theramore, the Horde didn’t care nor expect the citizens to leave the city.
In Teldrassil how many children died?
In Stormwind during the fire in the beginning of the expansion how many civilians died?
The Horde invaded and plagued the city of Gilneas killing countless children.
The Alliance almost never target children and intentionally target and attack the military only. In Dazar’alor the Alliance didn’t go into the civilian side parts of the city. They only cut swaths through the center of the city and only directly attacked militants.
Killing civilians is one thing, killing children is something the Alliance never intentionally did.
The Alliance of Lordaeron putting Horde in camps? That wasn’t the current Alliance of Stormwind and Khaz Modan. The same souls of people who put Orcs in camps are literally members of the Horde. Their the Forsaken. Those are the humans who worked against the original Horde.
Now this new Alliance after the fall of the Alliance of Lordaeron hasn’t done anything like that.
Horde at one point was fundamentally evil however I wouldn’t say they ‘love’ attacking children.
There are still some differences in the way Horde/Alliance operates.
When you’re helping the miners in Zuldazar as Alliance you’re setting them free, same with the Vulpera that the Sethrak enslave.
When you’re doing quests as Horde in Stormsong/Drustvar you’re killing the civilians that are trapped either by the animals or by the roots.
Alliance does have a cruel streak in terms of killing injured Horde soldiers on Alliance land during the incoming invasion to Kul Tiras/Drustvar and killing poisoned nearly dead soldiers near the Oceanic cove but those are soldiers rather than civilians - which in two of the cases are attacking Alliance bases directly.
I’m talking about why do the Horde constantly keep killing children
It’s not about killing civilians. Both factions do that. The children though like in Teldrassil and “almost” in Theramore. There were citizens in Theramore and the Horde planned to kill citizens. Children included.
Isn’t it only mentioned that Horde (more of rogue general who was just a mcguffin for foreshadowing) only killed one group of possible youth / children from the druid school in Stonetalon Mounts. canonically?
Thera(no)more children and elder where evacuated after Baine sent warning there.
Unless it is offically stated otherwise (and honestly to prevent a massive PR backlash) children are often depicted as being evacuated off screen for massive events like Theremore, Gilneas, and Teldrassil. Unless it directly for story/plot growth (i.e: plagueland quests has a ghost of child part of a quest.)
