I've always thought of 'eejit' as an affectionate insult coming from the word idiot. You know, when someone does, or says something a bit foolish, you call them an eejit.
I'm not sure what you're trying to explore, Peachy.
The recognition of another's emotions that you speak of is the same as the recognition of another's emotions in the case of the serial killer. They are both empathic experiences.
The difference is in how you interact with that empathic experience: whilst you would work towards alleviating pain and enjoy the experience of achieving that aim, the serial killer deliberately creates the pain and enjoys the experience of achieving that aim.
You are empowered by reaching your goal, the serial killer is empowered by reaching his, or hers.
All this talk of empathy and yet no one has defined which aspect of empathy to which they refer. That renders this discussion somewhat of a useless muddle.
