Some people argue that since the MBotF is "the real story" of its world, all deaths are pointless in the end, whether you go out like Trull, Kellanved & Dancer or Felisin Paran.
But in the case of Trull, there's been so much dying both before and after in the story that we don't need to be reminded once again that we live or die on a whim and that we'll all be gone soon whether we like it or not. His death was just a tad too harsh. Imo.
