You are misstating Darkcore41's argument.
Note that Darkcore41 does not argue that surrender would lead to an "automatic bad end". He is arguing that it would be ridiculous to hope that surrendering would be a good idea for many, many reasons. And then he articulated (logically) why doing something would be better.
And, as per usual, you mock anyone who differs from your opinon as "Leeroy Jenkins", "fear-mongering", and acting exasperated. Which, fair enough, have worked for enough votes in the quest that we are where we are (and also worked last quest). However, when one strikes out the over-the-top emotion and mockery, really, there is nothing to argue with.
Because you haven't really articulated a good point. Hopefully, enough voters will see that and vote for something that can actually lead to a good action.
To be fair, the QM has been very clear on his stance on our ability to butterfly away things- he does not believe core traits can be modified. I was unsure if the QM thought that Thanos' insanity was a core trait or something that came up because his world died. Now I can see, obviously, he believes that insanity is Thanos' core trait (which leads to a dark view on mental health- but that isn't a discussion for this thread and we already discussed this idea of core trait last quest).
