The dedicated followers of Ayn Rand are a perfect example.

At some level empathy is inate. Animals possess some degree of empathy, if not they will eat their babies.

Current research shows, those raised by atheists are more empathetic. Older research suggests higher degrees of intelligence yields higher degrees of empathy.

Religions likely formed to cope with death. It is a mechanism to cope with the sorrow from the death of loved ones and a comfort for some gripping the reality of their immortallity.

Religion teaches obedience and humility.

Its seems also to e prevalent with Libertarians. Rand Paul for instance appears to be void of empathy. The Libertarians I've met on the site equally seem to fit the description. They would as soon let someone suffer as long as nobody touches what they think is due them.

Sometimes empathy gets in the way of good judgement, and definitely affects making hard decisions about the lives of others....so lacking empathy can sometimes be a bonus.
How do you measure 'degree of empathy' .... what level is 'right'
I am unclear of your argument that religion, based on moral teachings, formed to make people more empathic ... instinctively seems like a deeply flawed assertion.

People are born with more or less empathy. One can learn what it means to be empathetic and learn how to express it, but for others it comes completely naturally.

Religion does NOT teach empathy or morality. It teaches that certain actions will be rewarded or punishable by God.

Having studied the Bible for too many years I can look back now and say that from my study I find little morality within its covers and what is in there would tend to stifle empathy. There are exceptions like the golden rule but I would say they are exceptions and not the rule.

No...I can’t concur with you on the idea that religion was formed in order to teach empathy via morals. Some people do have less empathy than others...however this is completely unrelated to whether they are religious or not. In my opinion, morality and empathy are both human characteristics, and were undoubtedly innate in humans before religion was invented, some people are just less moral or empathetic than others.
