Have you seen the panda that was raised by zookeepers? The zookeepers had to teach it to break bamboo, which was hard for them so they often grimaced while doing so. The panda learned to make a similar face, seeing it as part of the process. They’ve even caught the panda making the grimace after breaking the bamboo, like it realized that it forgot to do the thing and had to make up for skipping that step.
Sociopathy is the inability to feel empathy. This is not inherently a bad thing, it’s only bad when people use that to harm others.
A common trait for sociopaths is seeking success, which is defined differently in different cultures. In the US, success is usually defined by fame, money, or power, so we see a lot of sociopaths in government, C-suites, and Hollywood. However, in India, success is more defined around family involvement, and so sociopaths there are often seen establishing those strong family ties and working to fit in.
Some studies suggest that 4% of the population have the brain profile of sociopathy. That doesn’t mean 1/25 people is evil. But when someone who is sociopathic uses that lack of empathy to harm people, that’s when they become a danger and should be called out for it.
