Empath is a word usually used by someone diagnosed with sociopath, or sociopathic traits.

Someone, through no fault of their own, hasn't been able to develop emotions, perhaps due to frontal lobe damage, or more often, lack of emotional connection from their parents at an early stage. So compassion, guilt, remorse and shame is often alien to a sociopath or pshychopath. So Empath is a word used by people who cannot exprerience emotions to explain the rest of us that do experience a range of emotions such as empathy, guilt, shame remorse, affection, etc.

So if you haven't got sociopathic traits, then you are an empath.
