Good God people get a grip! You'd think with how much stuff is leaked on the interne, you all would know already why he looks like that.
So we're, what, supposed to accept it because he's got a condition?
Howzabout this? Howzabout we don't put in the usual "let's make the villain more human" Cliche ailment and just make him the fucking BAD GUY
, 'kay? How hard is that??
Thing of it is, that one of the (latter?) origins of the Commander would have been prefect for this day and age: A small business man that has a bad day-- brother killed, wife dumps him, and the IRS fucks him over-- he snaps, starts a massive pyramid scheme to fund his anti-govt. plans and actions, and as time goes on he goes from a small time militia-type nutjob to a full blown domestic and international terrorist threat.
Fucks, it's the two for one special: He's human-- he's joe every man in the current economy, and he's a major nutjob bad guy that only cares about bringing down the world govts.
