Eve is appealing to many because unlike other games those ways of behaviour are viable and potentially successful strategies. Just as they are in RL. To 5% of sociopathic people. Double or tripple that for Eve, because anonymity loosens some barriers, and because it’s a game.
I wouldn’t say they are the core of Eve though. It adds realism, makes your decisions and reputation more meaningful. Makes the community more vibrant.
But you still play with your friends, you still create a corp and alliance. You still trust some people. You communicate and cooperate. People still help each other, teach newer players.
You could still gank miners in RW sites, you know? So your hardboiled deceiving backstabber pvp BS talk is way off. Most people wouldn’t play if literally everyone would backstab and deceive. If you literally couldn’t trust anyone you would most likely play solo yourself.
