Yep, that's the truth! Armin really looks up to Erwin, to give you an idea or where that comes from. He admires people who are able to discard their humanity for the greater good... meanwhile Jean is the opposite, and believes that people should be told what they're dying for, even if the truth... sucks, to put it simply.

ah well, that's not so bad, at least. just a matter of staying on his good side, huh....
