Well, to get all hippy on everyone's ass, I firmly agree with the idea that a human can do whatever they want to their own standards and still lead a happy ,be it healthy or not, life.
Take the man in the story for example. He made the mistake of getting sucked into the great circle jerk of one's ego, which is of course any MMO(rpg, fps, puzzle). He neglected his responsibilities, which lost him his marriage, and left him for the game that made him happy. Like a previous poster said, men are simple creatures and will selflessly, depending on the willpower of the subject in mind, destroy everything around him in order to do the activity the man wants the most. He is most likely happy to be divorced, with little regret aside from the loss of a "loved" one, which fades in time in most cases. He will most likely continue to do what the mmorpg tells him to do until something better comes up such as another mmorpg, career oriented goals, another family, or any other goal mankind can make up. (war, romance, any type of meaning)
Take this situation out of societies' eyes, and you'll notice that there is nothing wrong with man's primal selfishness to acquire what he wants the most, but of course this is irrelevant and I'll be flamed for even bringing up a world that isn't based societies' standards.
I'll list the blame and where it should go:
The Husband: He is charged for addiction, which sprouts neglection, which sprouts in its most basic effect will push others that are not with you against you.
The Wife: She is charged with lack of interaction, idealized "TV therapy" (a sane aspect seems ridiculous), and supporting her husband's addiction by purchasing and funding his addiction.
The Video Game: This object is being charged of existing, corrupting millions by crippling the husband from his socially welcoming ideals, and profiting off this "sick" behavior.
For lack of better words, what does this even matter? If all of these ideas and objects exist, they should be put to use. I mean, thats what they are there for. Profit is a damn good idea, and its implemented EVERY day with some "social corrupt" concept, even though nearly all of these nouns bring people together with common ground.
Is that enough psycho babble for now? I could go on if you'd like. :2cents:
