recently got to the whole "let's throw namatame into the tv" scene in my rewatch of p4a and it's like. holy shit yosuke was just so ready to kill. hands down. is he okay. does... does he need someone to talk to??? why is this poor boy filled with so much insatiable bloodlust, atlus
AHHHH I WATCHED THAT SCENE YESTERDAY TOO YOSUKE went so hard there, like damn son look at his fury!!! I feel like the anime did such a great job at capturing yosuke's sensitivity towards the injustice that happened to saki and nanako and how he flinches everytime it's brought up, and it really helped contextualise his reaction in that scene.
I also really liked how after Yu talks him down Yosuke says something like how he'll always be watching, anytime anywhere (unfortunately I don't have a screenshot of that and my safe file is too far from that date so)
It's interesting because it's also something that sticks - in p4au when Adachi shows up again and people around them are in danger, Yosuke is immediately on the offensive, charging forward without thinking.
I think it's one of those things about Yosuke that's very well written and something I adore. As a character strength, Yosuke is extremely protective of the people around him - he looks out for his friends and makes sure they're okay, buys them food to keep them happy, etc. One of my favourite lines from him is when you add him to the party and he says this:
But this is also a strength that when flipped as a flaw is one of overprotectiveness. He becomes reckless and forgets to think rationally, so he throws himself in front of danger without flinching because he wants to keep others safe. It makes him behave recklessly because he's single mindedly focused on getting justice for those who were wronged or for preventing any more harm being done, without any consideration for potential side consequences.
