Do sociopaths recognize themselves as such?

Is it known whether or not sociopaths recognize themselves for what they are?

I know the woman claiming to be a sociopath who wrote that book a while ago said she recognized it in herself, so I’m just wondering if that’s the case (if it’s even known) with most sociopaths.

I’m very sure there was someone in my life who is a sociopath and it just makes me wonder if that person knows full well how they treat others, or if they might be oblivious.
