Connor is a psycho, but he know it, he accepted it, sometimes he even is willing to control this, and he is self-ironic. I think that’s why he wins. Because other psychopaths, who are unlucky enough to get on his way, – they are too self-righteous, too self-enamored.
Anyways, the main idea is be a psycho, train yourself, become proficient in killing people – and you’ll survive Armageddon 🤟
