I have always understood 'empathy' to mean 'walking in someone else's shoes'. In other words being able to share another person's feelings entirely at a time of trauma. I cannot see how anyone in any circumstances can do that.
I hope I can offer a person in distress support and understanding ie sympathy and, possibly, understand how I would feel in their circumstances, but I would never ever be so arrogant, or self-deceiving as to believe I could enter exactly into everything they are feeling - and what good would it do them if I did?
When my sister died, what I needed was people prepared to listen, to put an arm around me and make me tea, ie provide sympathy and understanding. The last thing I would have wanted was someone believing they could feel as I felt, and thinking that by being consumed by the grief that consumed me they could be doing anything other than adding to my woes. Empathy, at its best is patronising, at its worst..........
If a lack of empathy, means that all those that were so kind and sympathetic to me in my grief were psychpaths, they should be proud to be called so.
