Does it glorify such actions? The absence of parody, satire, condemnation or justification rooted loosely in one of those does not in turn mean glorification. Granted I tend to read things along the lines of "obviously I do not condemn these actions" in the same way as I read things that start "I'm not racist, but".
One being in their "right mind" that is an interesting question.
True, I realize that it's pretty narrow-minded to judge something without being given the full context, in this case a trailer for an unreleased game. But at the same time, it's what they chose to show and because it's all they provided me with, that's all I'll be going off of when formulating my opinion on it. You're right though, I used "glorification" in the wrong sense, implying that the makers of the game idolize the actions they depict.
The one stickler I have with it is that they chose the medium of video games as a means to roll out such imagery. I think that in today's society, video games are quickly (and simply) dismissed as a form of relaxation and and enjoyment. It's this statement that's kept the age old "video game violence=real life violence" debate just barely alive for years, in my opinion, and as such make for the argument that the makers of the game are assuming people take pleasure in senseless violence. I guess that's why I instinctively took up the idea that they were glorifying serial killers. It's interesting to think that if the trailer had included inter titles like "Enter the mind of a serial killer and take your vengeance" (which could be taken as the "message" of the game makers), the game wouldn't be up for nearly as much discussion as it is now with it's sort of 3rd person neutral stance of just watching a character be evil.
I suppose that mention of "evil" sort of segues into what the definition of one being in the "right mind".
First off, that sounds like a really cool book and I will be going to look for it (which I guess proves its point in a certain sense, lol). I completely agree that certain clinically-recognized traits of sociopaths are generally accepted, if not desired, by people. To me, in a nutshell, it seems like a result of the romanticizing of said mental states in the same way people portray suicidal tendencies as being the characteristics of a tragic, misunderstood hero.
