No, I don't think I'm a sociopath at all, but when I was learning about narcissism I had a lot of "well, that used to be me" moments. Not necessarily the borderline version but somewhere on the spectrum definitely.
But what I was trying to say is that I believe those predatory instincts are in all humans, healthy or otherwise. I realized pretty soon once I started self-work that I'm definitely not all sunshines and rainbows, at least as far as my thoughts and emotions and motivations go.
I also believe that none of that actually defines a person as long as it doesn't translate into behavior. You can't really harm anyone with your thoughts, and from what I've learned, those less-than-perfect thoughts can actually be quite useful in motivating you, understanding others, etc.. But that's a very long (and a bit controversial) conversation=)
