Can't disagree with
this more, although I can see where you're coming from.
That's what Takemura is, though. He's not your friend, and I honestly think it's to the game's credit that they fairly well trick you into thinking he is. I'm working on something longer about this right now, so I'm not going to try to go into it too much here, but I saw the Hanako / Johnny decision as about whether you trust Johnny to give you your body back or not once it's all done.
That said, I can totally understand why people would want some of the other side characters (LI or not) involved in the endings, even if I don't agree.
Maybe I need to replay the Devil ending, but I took it more as being shamed not for being selfish, but for trusting that the Arasakas would or even could keep their word over Alt. Which...yeah, I do have a problem with this, but for different reasons--that Alt is ultimately more trustworthy seems almost arbitrary, given what she is (and is willing to do).
