I love the premise of this story I just unfortunately feel like it hasn't been played out in the best way, I feel like the characters are very one dimensional and dont feel real. also It seems like the story jumps all over the place time wise without any transition.
In the comics it is said that you can't destroy the stones because if you destroy the stones you destroy a part of the universe.
Sacrificing the stones to the system, would wreck that universe.
