Maybe, just maybe, the fact that In-ho let his brother live was a call for help.
I don't want to play down the things he has done. They were horrible and caused people a lot of pain if they even survived.
However, I believe that In-ho saved his brother in the end. If he hadn't shot him, they'd probably both be dead by now because the soldiers would have killed Jun-ho and then him because he wasn't loyal. I think he instructed Captain Park to save Jun-ho and keep an eye on him. Yes, Park led Jun-ho the wrong way, but I think deep down, In-ho hopes that his brother will somehow find and save him.
There are so many signs that In-ho actually struggles with his situation and that there are still human emotions that deeply affect him. He still mourns his wife and his child after nine years. He cares about Jun-hee and the child, and I don't think he only pretends to do so, I think they remind him of his own past. He tears up (imo) when he tells Gi-hun that it's all over.
Maybe In-ho observed Gi-hun so closely because he wanted to gain back his trust in humanity. I think they're actually not so different. They experienced the same pain of not being able to save people they cared about, went through the same game and the money couldn't bring back what they lost. Still, Gi-hun chose another path than him to cope with his past. Maybe In-ho hopes to find a way back to his old self through Gi-hun and Jun-ho.
Maybe, deep down, he wishes to be able to go back, but he can't do it himself because of all the things he has done. Maybe he even thinks he doesn't deserve it.
End of brain rot.
Oof indeed.
I might me wrong in my theorizing, but I made a post about how In-ho's actions which started Jun-ho's investigation back in Season 1 was a subtle cry for help. What I'm inferring is, by ceasing to pay his rent, he actually may have wanted Jun-ho to start searching for him while he was drowning in the ocean of inhumanity that are the Squid Games.
And this makes me think about the series on two levels, because of course there's Gi-hun's story, the central one, which shines to the cameras and takes up all of the screen.
But every sunshine has its counterpart, its shadow - and this is Jun-ho and In-ho's story. Because in this line of thought, what actually started it all is is as much Gi-hun's entry into the games as the start of Jun-ho's investigation.
Maybe deep down In-ho never ceased to hope someone would drag him out of this (by force, and he possibly knows his brother is strong enough to get that for him, to rip him from the Games before they swallow him whole) just as much as we know from Lee Byung-hun's interview that he secretly hoped Gi-hun was right all along on the nature of humanity.
To me there's no doubt he is calling for help, even though he has ultimately rejected his brother a first time, even though it doesn't manifest in understandable ways from an outsider viewpoint. We have to remember he is broken. He was broken, molded and reshaped to fit every aspect of this insane machinery that are the Squid Games.
oh no, I want to do a corrupt cop Inho PWP. just him purposefully giving Gihun a hard time and having his way with him ๐
GIhun *being cuffed after getting creampied in the back of the police car*: but I thought you said you'd let me go if I... Inho *zipping up his pants*: I changed my mind. Seong Gihun, don't get it on my seat or I'll bump up your charges
