the Machine vs. Smartisan
S3E22中Decima头目Greer与Harold 对话：Harold表示自己被当作AI之父是意外的副作用。他对AI的诞生持悲观态度，因为自己不能控制其进化。对此Greer的态度非常明显——Uncertainty. Your personal abyss. 关于机器的建成，Greer一度认为是出于创造力而非利他主义。对此Harold承认，他的确感受到创造的力量，而同时也一直声明他建造机器是为了拯救生命。以S3E20结尾他不杀议员的抉择作例证，再合适不过。盾与剑，这也正是the Machine与Smartisan最大的区别。
Since we started this, things have changed.
We've changed.
But the mission, our purpose, has always been constant--
to save lives.
If that's changed somehow, if we're in a place now
where the machine is asking us to commit murder...
That's a place I can't go.
I'm afraid this is where I get off.
Vigilance vs. the Government
S3E19中Vigilance头目Collier与Harold同样也有一番对话，Harold坦言，他们可能难以相信，自己同意Vigilance的诉求，只是不赞成他们的暴力手段。在S3E23的审判中，我实在为Harold的勇气所折服，他与Collier激烈争辩：从建造机器的第一天起，他就在担心它可能造成的危害，他对自己的作品感到不安，始终不敢说自己做这件事是否正确。如此强烈的道德感甚至可以用珍贵来形容。Nothing wrong with a dictatorship, so long as you're the dictator. 这恐怕是Collier能够给Harold的最高敬意。Harold承担责任的勇气和为此付出的一切，S3E21中他将被交给Decima时展露无遗。
From the day the machine went online,
part of me knew that I would never be able to sever myself from it...
And that anyone I ever cared about was in danger.
It was foolish to imagine otherwise.
I tried to guard myself, stay hidden,
from the government, the authorities, people looking.
Here we still are.
This moment was inevitable.
This moment was always looking for me.
I have to accept it.
Carter & Reese
Carter的意外死亡给Reese带来沉重的打击，他开始怀疑，怀疑机器存在的意义，怀疑救人的意义。他堕入虚无的深渊，或许救与不救没有区别，人总有一死，不过早晚。而此时Harold了解这些，也同样悲痛。剧情至此提出一个相当艰难的问题——如何与不可避免的结局抗争。在Harold与重整旗鼓的团队身上，我仿佛看到加缪《鼠疫》中的里厄医生，这奋力的反抗分明是人道主义之光。
The machine only gives us numbers,
because I would always rather that
a human element remain in determining
something so critical as someone's fate.
We have free will.
And with that comes great responsibility
and sometimes great loss.
I miss her dearly too.
然而我们不可避免一个问题，坚守这样的道德观，其意义何在。其实Harold的道德观相当精英主义，真正的精英主义。也难怪S4E01中安排Harold为客座教授时，他所教授的课题是the ethics of high-frequency decision making 对高频决策的伦理考量。这正是Harold日夜面对的难题，也是唯Harold才有资格讲授的课题。可是面对空荡的教室，Harold与他的课题究竟该何去何从？
