It's fair that you're upset about this! Mizz can be a very difficult character in quite a few regards, and you've definitely hit on one there. I'm not going to tell you that you're wrong not to like it, of course; you're very allowed to be!
I was tempted to try and go point-counterpoint here, but the only thing I'll suggest is that Rael has his own thoughts and feelings on matters and, as much as I've tried to give readers the chance to shape and direct him as they like, I can only do so much there . I'm sorry that the situation that rose through your choices wasn't one you liked, and that the way it played out made it worse, but that's the nature of choices!
Other ones may have ended up better or worse for you, but this is what you got this time. Thankfully, Void Dreaming thrives on trying different things and alternate paths; you can always try something different!
