If you think about it, he’s the greatest protector of a kingdom that is completely using him.
With King Calvus’ participation in the Order of Aesir, Julian would most likely end up with a devourer in his chest given that he’s got a powerful curse as soon as they don’t need him anymore.
Wdym? He didn’t have enough showtime to be called asshole. Even when he was rude after striking down MC, its could have been caused by his relationship with Argos. He also probably knew consequences of our actions (just like Calvus), so obviously he was angry.
Bro just tried to defend his country lol. Some noname came and destroyed their last naval base, killed their general and put treaty between kingdoms into danger. What did you expect to hear from him after that?
To be fair, Argos was a general, and anyone with enough strength to take him down along with an entire fort is usually a considerable threat. And while he knew that Argos’s prowess was declining as he continued to age, he didn’t think it was bad enough to the point that the MC was able to beat him.

Umm, ackshually, his first line was “I’VE FINALLY FOUND YOU!!!”
