The scientific evidence for fixed male or female genetic traits as they relate to caring attitudes are shaky at best. At worst, there is no evidence to support your belief.

The danger of believing caring traits are genetic is that genetics are fixed, cultural influences are less so.

So lets see caring traits as cultural and adaptable, and let's encourage all men to be more caring to other people, rather than believing men care more about things and not people - that belief can be very harmful. Humans are very adaptable in general, we can all make more effort to care for others, even in spite of genetics.
