He didn’t call out to them after they beat him up. He saw them, called out to them, then they started beating him up. Why would he think he was in danger before calling them out? They didn’t notice him until he did. There was never any indication that he’d be in danger.
The first thing he tried to do after they started beating him up was give them money because he thought they were extorting him. Obviously he got that wrong, but my point is that he understood that they had bad intentions for him, even if he didn’t specifically know why.
And I’m not saying he’s not a KY. But since you brought them up, I can tell you that’s actually part of what I’m saying. He was unable to read the particular nuances of those situations, but like I said, he clearly understood the hostility from those people in that first encounter. Hence why I’m saying it’d be arbitrary if body language was included. Body language can not convey specific ideas in that encounter. Only hostility could be understood, but not the reason for that hostility or how far that hostility goes, at least until they were preparing to execute him, at which point it’s obvious that they were going to kill him (well, it’s also be obvious after beating him long and hard enough).
