Locus on the other hand, he seems to be more emotionally vulnerable, he has a dissosiative personality disorder brought on by PTSD. He created a persona for himself to explain to his own mind the atrocities he is commiting, tricking himself into believing that he is not actually responsible for his actions. The real him is still inside of him though as Washington has made a point of showing in season 12 during their final encounter, which means that if that switch is flipped, Locus himself might go completely off the deep end. In other words, he may completely shut down or lose his original self for good, in which case Felix would have the upper hand

A good analogy for this would be that Felix is the Joker from Batman, remorseless, wanting to spread anarchy and destruction, but keeps himself in check with his fake emotion to bring about his end goal (like how the Joker treats Harley Quinn)

While Locus is the Hulk from the comic of the same name, His outer personality being the Hulk to keep his inner self protected, but if his inner self gets damaged, Hulk will come out to play
