Skoll Shorties

There was zero justification for the first and second war. From any outside perspective, the horde were the villains in Warcraft 1 and 2. The orcs who didn't want to be villains got kicked out

They realistically didn't have any choice in the manner at that point. They were slaves to the Legion and were lied to. It was only because of the fact Orgrim never drank could he aid in getting his people out from their shackles. It's why Orgrim is viewed as a good Warchief.

He still actively led a slaughter campaign against the races of azeroth. And that is, as you said, -without- the demon blood.

He did his with purpose and it wasn't out of vile action either. Orcs & Humans have both gone to war with each other for ages & none of them are villains for it except from the perspective of the other side. Orgrim went to war with the Humans for their planet as theirs was gone.

He didn't have to chase the alliance across the bay to claim a home for the orcs. I am one of the biggest orc fans out there, but there is no world in which the first and second wars don't sit squarely on the horde's shoulders.

Just because there is some mental justification doesn't make them not the villain. Every villain believes they are justified.

I personally don't see Orgrim Doomhammer as a villain of the Horde. For the Alliance? Most definitely. But for the Horde? Nah. That's where things get tricky.

He was decidedly a villain for the story of the setting at the time, regardless. The horde as a whole villains for the setting at the time. It's like saying Arthas wasn't a villain from the Scourge's perspective. Just because you could play them doesn't mean they were good guys.
