It is possible for everyone to have empathy for other humans yes. It should be expected. The problem is that it is not expected or even supported by broader society.
I would advise some caution conflating empathy with caring. Many NDs have decreased–or possibly even a lack of–empathy due to the construction of their brain. This does not mean that they do not care, though. Even a lack of empathy is no excuse, NTs just fuckin hate us.
