Again, that is only the surface level constant misapplication of the meaning of compassion to empathy, not empathy itself. Empathy is derived from the German word
Einfühlung, loosely meaning "feeling into" (and one of three words coined for this purpose of describing aspects of feeling art on different aspects; the other two being Zufühlung or "feeling towards" the sensory properties, such as brightness and color, and Nachfühlung, or "feeling along", meaning the motor properties, e.g. the sense of motion or stillness imparted)
, and is from a theory of art appreciation that maintains appreciation depends on the viewer's ability to project their personality into the viewed object. It then came to be applied to people in much the same way, the projection of one's personality into the shoes of another person, with the goal of
understanding how it feels to be in that position. It's nothing about
actually feeling how they feel, just understanding how and why they feel the way they feel so you can properly communicate.
Now, to address your second point and the aspersions you have cast upon me; No, empathy is not a sin. The effort to ascribe the positive connotations of compassion to empathy was in regards to its potential for abuse as a tool for manipulation. This isn't a new concept, either; Even the original 1990 paper on Emotional Intelligence by Salovey and Meyer speaks of Social Intelligence (the umbrella set to which emotional intelligence, and thus empathy, belongs to) as, "the ability to understand and manage people", and that Thorndike, who initially coined the term to differentiate it from rational intelligence (aka "intelligence" as we know it sans sociology), defined it as "the ability to perceive one's own and others' internal states, motives, and behaviors, and to act toward them optimally on the basis of that Information". Yet even they acknowledge that it often is noted that social Intelligence, "boils down to the ability to manipulate the responses of others ... " and acknowledges that, while crassly put, "The essential thing is that the person ... is able to get others consistently and voluntarily to do the things he wants them to do and even like doing so ..." is accurate to the concept. It is about manipulation at its core. Even for emotional intelligence separate from social intelligence (that is, as the subset alone), they note that, "interpersonal intelligence involves, among other things, the ability to monitor others' moods and temperaments and to enlist such knowledge into the service of predicting their future behavior", again acknowledging that even their subset is about manipulation of others through the understanding of them. That does not mean it is intrinsically BAD, but it could very easily be used for evil purposes with little effort, and is, most commonly by narcissists.
