A minor copyediting suggestion (adding the words in bold):
Factor 1—characterized by cruelty, grandiosity, manipulativeness, and a lack of guilt—arguably represents the core personality traits of psychopathy. However, scoring highly on factor 2—characterized by impulsivity, reactive anger, and lack of realistic goals—is less problematic from our perspective. In fact, humans scoring high on factor 1 but low on factor 2 are probably more dangerous than humans scoring high on both factors (more on this below).
It’s not a big deal, but it took me a minute to understand why you were saying it’s both less problematic and more dangerous.

Thanks! Added your suggestion.
