em·pa·thy
/ˈempəTHē/
noun
- the ability to understand and share the feelings of another.
Actually we have more empathy for people who are hurting through no fault of their own while not as much for people who chose to hurt themselves and others. It doesn't make sense to us that people would want to harm others, especially in a way that causes themselves a loss, but it's imperative to others that they behave in a socially acceptable way, which means not considering the understanding or feelings of persons who are different.
Everybody knows it's wrong to lie, cheat, steal, maim, and murder others. Most people, not just psychopaths and sociopaths, chose to disregard this understanding and not share the feelings of others in favor of believing that it's OK for them to do whatever they chose, just not for others to do bad things to them. Doing bad things to people who are labelled as different is what society teaches. Most people simply act on social cues in the way they were raised to respond. Those on the spectrum can't do that because they are blinded to social cues by the Autism. Information is being with held from us that is not being with held from NTs. Our thought processes are more unique. We have to rely on actually thinking and feeling to process each individual response, without the extra information of social cues and preprogrammed automatic reactions from irrational training. All people have empathy, but the masses don't use it very often and view empathy toward popular people as being true empathy but empathy, toward a person who is not of their particular group, as insignificant and therefore discard it as not recogniseable.
Because of our neurodiversity, we are singled out for all sorts of abuse, so we know firsthand how much it hurts to be betrayed, beaten, bullied, excluded from employment, healthcare, housing, public accomodation, relationships and all other social amenities - simply because we were born with a brain anomaly that impairs our ability to lie and hate for no reason. We are routinely misinterpreted, misquoted, misjudged, misdiagnosed, maliciously maligned and otherwise mistreated due to other people's unwillingness to be empathetic.
