Obviously I do not understand your argument then. I have no idea what you meant by "resonance cascade" written in red, for one thing. Or any of this finger on the nuclear button stuff.
I would suggest -- and this is me being very serious, here -- that perhaps what is wrong with my posts, then, is my assumption that you are aware of the base material, Puella Magi Madoka Magica.
In that material,
all of Madoka Kaname's friends get themselves killed, and this prompts her to sacrifice her presence in reality to become a metaphysical law with the power to do better by them.
The implications of Resonance Cascade are myriad and poorly defined. If you read things closely, you will glean that it was supposed to be, generally speaking, ominous and
very very bad. One of the primary themes of PMMM was how one person dying, getting killed, turning into a witch, etc. would lead to everyone else going the same route in short order. Thus, the implication I am making -- and that Resonance Cascade as a potential chapter title makes -- is that
somebody fucking dies (Sayaka, who is very skilled at getting herself killed, as you would be aware if you knew the source material) and then
somebody else fucking dies as a result.
We do not want to enter Resonance Cascade. It presents an incredible chance of bad-ending the quest.
Your argument about "not basing our choices on the opinions of a child" is... it's
literally comically stupid in the context of PMMM. If Sayaka decides she doesn't like what we're doing, she will break from us. On her own, Sayaka has, for a hundred or so loops, consistently managed to either get herself killed or turn into a witch. She runs off on her own after getting upset at the people who are trying to help her, she builds up grief, acts irrationally, and then fucking dies. The implication made by the source material is that she does this on a regular basis, virtually every loop.
In the source material, this is followed within ten or so minutes of screen time by Kyouko killing herself trying to talk down Sayaka's witch.
Before all of that, Mami fucks up and dies, and her death creates a rift between Sayaka and... everyone else.
If we do something to cause Sayaka to split off from us and go do her own thing, this is not a setting where we can just take her in hand and ignore her opinions and treat her like a child.
If we do something to cause Sayaka to split off from us and go do her own thing, then statistically speaking, the odds are that she will get herself fucking killed within a couple days.
If Sayaka gets herself killed, Madoka will be stressed by it. We will be one giant step closer to bad-ending the quest with Madoka doing something to make Homura loop out (i.e., making a wish).
All of that is literally what happens in the source material. Kyouko and Homura try to help Sayaka, but she is convinced that they are bad people because she does not like the decisions they have made, and so she refuses their help, which causes her death, which causes Kyouko's death, and all of this leads up to Homura eventually choosing to let herself die/witch to Walpurgisnacht, at which point Madoka breaks the universe with a miracle.
Do you understand why I am so offended by the argument you made, now?
