Delving into my hatred of the end of Divergent

I think I realized why before I was so upset at the ending of the Divergent books. So the whole time it was from Tris' perspective. The last book switched on and off form Tris to Tobias. But when Tris died, it wasn't even from Tobias's perspective, it was from what would have been Tris's perspective. That is not okay. That is cruel and it makes me uncomfortable. It....its not right. Its just not right.
