> Are you suggesting boys are less empathetic than girls?

Girls exhibit greater empathy than boys following a minor accident Joyce F Benenson et al. Sci Rep. 2021.
ABSTRACT
Hundreds of studies find that girls and women report feeling greater empathy than boys and men in response to adverse events befalling others.
[...]
These behavioral results suggest that an adverse event produces different subjective experiences in females than males that motivate objectively different behaviors, consistent with findings from self-report measures of empathy.
Plenty of reasons for this other than feelings of empathy. Amusingly, history shows that queens are statistically more likely to start wars than men (not that I think this is particularly relevant to the question): https://qz.com/967895/throughout-history-women-rulers-were-m...

That's mostly behind a paywall; from the abstract I can't see how it distinguishes between experiencing empathy vs reacting to social norms or expectations of behaviour.
It's up to you to explore this topic for yourself, if you choose.

Studies in nonhuman animals and younger human populations (infants/children) offer converging evidence that sex differences in empathy have phylogenetic and ontogenetic roots in biology and are not merely cultural byproducts driven by socialization. We review how these differences may have arisen in response to males' and females' different roles throughout evolution. Examinations of the neurobiological underpinnings of empathy reveal important quantitative gender differences in the basic networks involved in affective and cognitive forms of empathy, as well as a qualitative divergence between the sexes in how emotional information is integrated to support decision making processes.
