Here's my take: He has committed himself to a goal that he views as essential to the survival of humanity. Thus in his zealousness, he will sacrifice anything, especially actual humans, to accomplish his "goal".
There was a time when I believed in his goal, but I've long since seen that the road to hell is paved with good intentions. He's happy to let Tesla factory workers injure and overwork themselves without fair representation. He views working at Tesla as analogous to "being in the special forces" (translation: sacrifice your life without fair compensation, then get thrown away when it suits him).
The inability of Tesla to remove Musk from power merely confirms the obvious fact that he stacked the board with yes-men. I have nothing but disgust for the army of Tesla fanboys who claim any valid criticism is really just FUD spread by shorts.
