I cheer myself up by ignoring the bios as a whole story and only implementing the things I do like about them in my own mind. For me they're so weak in the storytelling and character profiling that it holds no power with my imagination.
Scott is just creating cheap shock value in killing off 8 back original & other important characters. Might be be trying to copy what the Transformers movie (animated) did, where many Autobots died in battle, I hope he doesn't make the fatal mistake of killing off the main hero too!!
For me, these shock points don't work in small bios, but he wants to tell his story of MOTU through them and some do like it, more power to then if they do. I sure don't but I get a chuckle head and there with them.
See it as an alternate universe much like DC Earth 2, Marvel Ultimate, MC2 worlds. MVC MOTU even explored an alternate Eternia.
