For all of Jess's grandiose talk about avenging ancient ethnic cleansing (inexcusable war crimes), his true motivation revealed itself: he wanted revenge for the inhumane experimentation on Aisha, and he seems to have inherited the demon lord's power from her life's sacrifice if the markings on her mangled body are any indication.
