I feel like this problem is much larger than to the Pure Evil wiki, or the good/evil alignment wikis that have recently came out since someone on the internet decided to make movie criticism objective rather than keeping it subjective like it actually is.

Basically how the articles on the wiki go is it lists every terrible thing the character has done, and some points range from valid to being childish. For example here's a point in Aldrich Killian wiki page:

"He tore many of Stark's armors and suits with his Extremis powers during the final battle on Roxxon Docks, leaving Stark to his last set of resources to take him on... Not to mention, all of these armors are robots that are capable of showing sentience, so these all count as kills on his part."

This point is very bad because during active combat of course your opponent is going to try to take away every advantage the hero holds, and in this case Aldrich would destroy Stark's iron armors to get to his enemy. Also the last part is really bad, too, as far as we know JARVIS controlled most of these suits, I doubt he felt pain when they got ripped apart and I don't know if Killian even knew he was killing robot suits with some sentience. As far as we know the Iron Man suits, in the third movie, do not possess any sentience to be considered innocent lives Killian took away. So we're already off to a rough start.

Let's look at Syndrome from the Incredibles and this is what we get first:

"While he started off as a nice kid who admired Mr. Incredible (if a bit overly obsessed), he threw all of that aside as he grew up, subverting every potential redeeming quality."

Honestly this is where I think the authors just try hard to convince reader the guy is pure evil with no redeeming qualities with this sentence. The lack of redeeming qualities we do not see in the movie do not mean he had none of them even at his worst point in life, we simply don't know because the movie chose to focus on his bad side.

"He was already very arrogant and ignorant as a child, as shown when he went into Bob's car without permission and even claimed that he didn't have to worry about training him because he, as Mr. Incredible's biggest fan, already knows everything he knows. While Bob did push him out, it's only because IncrediBoy was doing nothing but annoying him and interfering with his heroics."

God forbid a kid is arrogant and ignorant, this argument is really bad since a lot of kids can be douchebags or egotistical because they are young, of course they will be selfish. To make this a point about why Syndrome is or was destined to be pure evil is really forced. The wiki page could've just sticked to the actual crimes Syndrome was committing in the main plot of the movie to make a point instead of going as far as prologue to say "He was even pure evil as a child!"

I could go through other points the wiki page tries to make but this thread is already getting very long, so I'll cut to the point I wanna make.

There are and can be pure evil characters devoid of any good qualities like archdemon from the Dragon Age franchise, the devil Judge Holden, Freddy Krueger, Dark Urge before amnesia and so on, but there is a difference between absence of good qualities and lack of good qualities we see in the villains. A movie or show doesn't always focus on all qualities of a character and so we won't see few redeeming qualities a villain might have since writer could not think of them, or it'd not be important for the story, and categorizing characters lacking good qualities as pure evil is really illiterate. Are characters like Syndrome and Killian evil? Of course they are. Are they pure evil? No, they aren't as terrible as some actually heinous villains in numerous stories, they are just simply evil characters lacking redeeming qualities and that's just it. Classifying characters with lack of good traits as pure evil is a sign of media illiteracy which is plaguing the internet now. I don't think this post is going to accomplish anything, but I wanted to vent my thoughts online and say objectivity is ruining discourse around the media.

Thanks for reading.
