as I've said before, Chris' character flaws are fairly common: he's selfish, lazy, and delusional. the main difference is that he takes this to 11, way beyond the typical lolcow.
For those who think Chris-chan is an asshole, I think they're misinterpreting him. His actions can seem that way, but he really doesn't have a malicious character. Rather, Chris is like a spoiled child who thinks their spur-of-the-moment desires are Good, and anything getting in the way of that is Bad. He has a bizarre logic and morality, distorted around his personal ego and id, much like a funhouse mirror. This leads to him being simply being incongruent with the real world more than anything. His patent disregard for the culture, society, and reality surrounding him lead to various results, some ridiculous, some very harmful (like the latest saga). But that's who Chris is. He's not someone who uses his powers for evil, rather, he's inept to the point that he doesn't realize when he's wrong.
I expect some to disagree, but keep in mind, this really does explain alot of his antics. Everything from the attraction signs and his conflicts with Jerkops, to Mary Lee Walsh, to wasting his welfare checks, etc. As for the latest saga, I think his desperation for sexual intimacy overcame natural barriers like the Westermarck Effect, and he simply molested the most convenient female person. As always, it's about him, and his short-term wants, he is simply incapable of thinking beyond this.
