It's that, but hopefully there's a bit more to it. For Rintor, it's a matter of profoundly distrusting the military way of doing things and disliking ambitious people and being commanded. He's been turned into a killing machine before by that same system, and he's deeply wary of it. He's aged beyond his years by some of the things that he's seen and done and in addition to his guilty conscience and fear of shedding blood, he probably suffers from some degree of PTSD.
