Exactly.

For the Fascists, the ones they see as lesser are pretty much sub-human and to be treated as vermin, and they have no more empathy for the younger "vermin" than they have for the adult "vermin".

Just look at Nazi Germany and Zionist Israel for very obvious examples of how for these people the children of the "lesser" races aren't really human and get targetted same as all the other members of the ethnicities they literally call "vermin".

If these people were both capable of empathy and unable to block their empathy on a per-ethnicity basis, they wouldn't be Fascists.
