One quick question then: How do you know psychopaths don't have emotions? I'm sure they do.
I am talking about the people without empathy. Feelings are often conjured through others, that is, if you are mad, I will be mad, if you are happy, I will probably also become happy.
In the cases of lack of empathy, there will be a basal lack of understanding between people. If you lack empathy, you will not be able to tell if a person is feeling fear, for example. If you can't read another person's face, you will not be able to tell if you are doing them any harm.
As already mentioned a couple of times, this is all hypothetical, and I don't have any education on this. My only knowledge comes from various articles I might have stumbled upon. This means that it is all speculations. My opinion, if you will.
So, let's assume you are unable to read other people's emotions and thus lack an understanding of non-verbal communication. You see people do something, but don't know what it is. You might try to mimic the movements and expressions that people make, and learn to mimic it at the right expression in the right time to seem normal. You don't understand the use, but you understand that you need to - fit in, if you will. Be one of them.
Just, that you are not one of them. You don't have to be like them, but it is easier to get them to do what you want, if you do what they do, and manipulate them without them noticing.
So, you don't understand these feelings, you just understand the concept of them. Someone tells you how it is to be in love, and you will use that to mimic the feeling. Someone will tell you that if you don't care about other people, you are evil. You don't care about other people, you don't mind that you don't care either, so you must be evil. Does it feel wrong to be evil? No, because there is no remorse, no sadness, no loss, no nothing to make you feel like what you are doing is wrong.
In past wars (when people were fighting face to face), about 2 percent of the soldiers would be able to kill other humans without being completely traumatized. You get traumatized if you observe the fear and horror in another human being's face when you are about to kill them, because no matter if they are enemies, if they are of another ethnicity, anything, they are still humans and still show the same emotions as you do.
Now, out of the last 2 percent that were able to kill, one half did so because they were able to set themselves aside and force themselves to work to be sure no one else would have to.
The other half were psychopaths. Unable to understand the fear, it would be nothing but a mere game, an easy task.
Now, while we are at soldiers.
Society says that killing others is evil.
Soldiers kill others, yet they are not evil.
If they tell themselves that what they do is wrong, they would go crazy. They will have to keep a distance to everything, even the norms of society, and justify their actions.
In reality, they still kill.
Anywho, enough with this. I hope I made myself clear, if not, I will just say that normal humans are not evil, even if they do "evil" deeds. Whether or not it counts for mentally ill persons is another discussion, that could probably go in the World Section.
Nice to discuss with you, Possum. Was interesting.
