so now its official that Armin is already dead. I still cant forgive those two f**kers, I dont know what motive does these two have, dont care about these so called warrior motivation. Their action should be never forgiven (annie included). they basically have like 5 years to think about whether their action is justified or not.
The most suitable punishment for these 3 and other people behind humanity extinction plan is to be haunted by all people that they murdered for the rest of their lives, they cant sleep it off or kill them selves. They eventually will give in to their insanity and die because of it in the most horrible ways.
