I wonder if you are mistaking an empathic person for a good person. Some people possessing overactive empathy react to someone in pain with anger: "It hurts to see this person suffer. Its their fault I'm in pain. How dare they cry in front of me!? I'm going to bully and insult this person until they quit this job!" This is an extremely common mindset at workplaces in my country of residence. Being empathic does not stop someone from being a donkeyhole. Empathy is an instinct, not a personality trait.
No. It is not real, people dont really care. Empathy comes from ego "I am more human couse FEEL others pain", is pure vanity. Fake it till you make it.
Humans dont care what happens to other humans, not even family, they only care about family around them becouse if something happens to them they will feel afected. If they die, there will be a hole in your space. Like not being able to get rid of that old t-shirt.
Spend 10 years away from your family in a rather "normal" life style. You will find out that if mom or sister dies, it will affect you, but not that much, your life must go on, right?
"overactive empathy react to someone in pain with anger:"
No they dont, people suffering are annoying, sorry, But they are.
People sincere with themselves like psychopaths just express it. How many times have you just avoided a "kind of close" friend becouse he was going through a break up and you just didnt want to hear his bullshit? Well that is normal.
We are all assholes.
Now I am gonna put it this way: If we werent assholes, we wouldnt have wars, or cheating, or laws, or need police officers, or a door in our house.
We are egotistical assholes, dont get me wrong, that is good, is what makes us push over the limit "I wanna be better" "I wanna be richer", I want, I want, I want.
Embrace the asshole, after all, you only got one. (see what I did there)
