Perhaps. However, Toxic or rather, "hypermasculinity" can be the result of emasculation. "Emasculation" really only exists due to the idea or conception of what it means to be masculine in the first place.
So from that perspective, you could argue that the emasculation you're referring to, the anger bitterness and envy that you alluded to, is a direct correlation to masculinity. You can't be emasculated w/o the idea of masculinity and if your response is to kill everyone when you've been emasculated, then that is directly tied to hypermasculinity.
And I agree that male aggression and violence is at this point innate. But I think we can both agree that something has to be done to tame that aggression down significantly. What that something is? Idk.
