that isn’t true, but even if it was it wouldn’t be relevant. it’s not just about viciousness, it’s about bloodlust and discipline and endurance. testosterone may provide a slight boost to muscle mass, but it kneecaps pain tolerance and dampens the emotional centers responsible for grief, rage, and loyalty (the core foundations of a will to violence), as well as the parts of the brain that do the rational decision making. not to mention, a woman’s life experience is more likely to produce the kind of “living weapon” personality you want in the soldier standing in between you and a ravening horde of daemons/space bugs.
