Virtual Morality Gives Pause For Thought

Thanks to Globeandmail.com for their article discussing deeper storylines and more complex moral choices for a maturing videogame audience. They cite a forum post from a KOTOR player lamenting: "Being evil is addictive and I find myself in situations where my conscience kicks in and it's difficult for me to do the bad thing", and the article claims this "...represents a new generation of sophisticated electronic games, created for a maturing and rapidly expanding audience, that are transforming gaming consoles from an adolescent diversion into a mainstream entertainment medium with artistic integrity and a social conscience." Is it justified to feel guilty about being evil within a videogame?
