How moral is your character? Where would they be placed on a traditional alignment chart?
Tyson would be a lawful neutral, almost a true neutral but closer to evil than good.
Good - Neutral - Evil
Tyson has a moral code that he follows but because his job means blindly serving others regardless of his own views Tyson has bent the needle on his moral compass enough that he can use other people’s compasses. Tyson’s morals change depending on who he is around.
Example: When around Moriarty murder is fine, everything is fine, so long as he remains loyal to Jim despite that he has described Jim as follows, “Some men follow their moral compass like a golden thread. Others let it sway with every step. Jim, well, he uses his moral compass as a yo-yo.”
Tyson’s behaviour and views change depending on who he is around, so when he is alone and following his own he keeps to his own views which are mostly moral and correct.
When he is following his own compass he tries to be good - he does his best to help people and make people happy at the cost of his own happiness - so he could never be evil but, even [especially] to his own mind, he has done far too much bad to ever be good.
Lawful - Neutral - Chaotic
Tyson has far too many [nervous/OCD/general] ticks and routines, is far too predictable, to be chaotic or neutral. He has created too much structure in his life to be anything but lawful. Even the way he chooses when to be good or bad is lawful, it is dictated by those he is around rather than chance or his own opinions.
But he is mentally unstable enough to almost be a neutral. He is just after the boarder. Over time as he becomes more and more derailed he may drift over to being a neutral, though it is highly unlikely that he could ever loose enough of his ticks and routines to go over to chaotic.
