Does Catholic morality (i.e. Natural Law) reject the idea that different cultures fundamentally think differently?

In the aftermath of the attack on Israel by Hamas, I've been listening to Ben Shapiro saying some things that I would like to know if are in-line with Catholic morality. It doesn't much matter what my opinion on the Israeli response to the attack is, but is the moral tone that Ben Shapiro is setting where he has repeatedly said that people who appear indoctrinated to value what they consider martyrdom over any other good are fundamentally on a different plane and not possible to reason with or treat in any other way than as if they were inhuman in accord with Catholic morality. Or does the Natural Law say that objective morality (i.e. not murdering - which is always wrong according to the Catechism) is accessible to even people who are brought up in a disordered value system?
