On the other hand, I've seen things that are horrendously absurd in game lore terms. The other day, for example, I've seen a lvl 60 Tauren druid trying to kill the supreme leader of the Cenarion Circle (sorry, I don't remember his name) in Darnassus! I tought: "OMGWTF!1!??/", and just stayed there watching...
Now, an off-topic reply to this comment of yours:
It reminds me of the 60's in comic books when "evil" was Russian or Poor and "good" was Capitalist or Rich.
Note: below I talk a little about politics and related themes. So, to those who don't like this subject I suggest you please ignore it and jump to the next post. Also, I don't intend to write about this subject again in this forum, for I know it IS off topic. If anyone wanna talk about it in pvt feel free to send me an e-mail: alexgieg ~AT~ gmail ~DOT~ com.
The situation wasn't exactly as you describe. One of the big villains of the all time was and still is Lex Luthor, whose villany comes entirely from his money, while one of the most famous heroes was and still is the Green Archer, a very radical anti-capitalist. On the other hand, today's climate in American comics if far from equilibrated: I purchase lots of it and found it very difficult to find any story where big corporations, republicans, conservatives, christians, pro-life, Bush and the like, with few exceptions, aren't compared to or actually taken as villains, while NGOs, democrats, liberals, atheists, pro-choice, the UN etc. are seen as the good and heroic guys. Typical examples are Marvel's "Supreme Power" and "The Ultimates", and DC's "Lex Luthor President". In other words, today's manichaeism is as strong as in the past, with the only difference being that now it works in the opposite direction.
Regarding Russia in the 60's, there were pretty solid reasons for it to be seen as a great villain at the time, even more than common politics. They were all exposed in the soviet premier Krushev's report about Stalin's era, made known to the world around the end of the 50's. It showed in practice, and above any doubt, what each and every student of ancient philosophy already took for granted: that an ideological system that says that the world will become a better place when this or that group of people is destroyed (no matter what each individual of that group say or do) cannot become anything other than genocydal when obtaining real power.
An example that everyone knows are the nazis. They preached that by eliminating the Jews the world would become a paradise, so, once with absolute power they did just that, taking that belief to their logical consequences. Another example well known is the French Revolution, to whom the world would become an excelent place when each and every noble were dead, what took definitive form in Robespierre's Terror. And a third example, very similar to both but which many people still try not to acknowledge, is socialism. Socialists also preached (and still preach) that when the rich are eliminated the world would/will become a better place, so, once with absolute power they did just that, resulting in Stalin's 20 million civilian murders, Mao's 60 million, Pol Pot's 2 million, Hussein's 300 thousand, Castros' 20 thousand, and so on.
Capitalism and capitalists, on the other hand, don't usually believe that a group should be genocided for the world to become a better place, so no capitalist regime, even the most dictatorial ones (who are evil, no doubt about that) has ever reached the same level of evil created by those. Capitalists can be a very egotist group, but this egotism takes a personal shape that gets satiated once a limited, concrete goal is reached. Such limits don't exist nor take any role among those who believe that History is theirs to rework and reshape no matter what, for they believe that anything they do, here and now, is justified by the glorious future they envision, and for which they most of the time work selflessly.
BTW, it's interesting to see how WoW's lore reflect all these things. Altough the Horde and the Alliance fight, both fight for concrete and usually egotistic things: more natural resources for their people (Orcs), their ancestor's land (Night Elves), their lives (almost everyone). As a result, their wars are never all encompassing, "take no survivors" ones. On the other hand, the Burning Legion's objectives are purely ideological ones: the world is an error, life is an error, true peace and true good will only exist when all that's wrong is erradicated, so let's fight ceaselessly to bring our universal utopy to fruition. There's no possible doubt about who are the villains and who're the heroes, even when the heroes sometime also fight among themselves.
