@Fa5t3r - People don't work that way. I don't think it should be up to anyone except victims and descendants of victims to decide how something should be remembered.
Respect means different things to different people. I remember taking a tour in one of the London experiences where they had people in costumes reenacting different horrible events from history and were trying to scare the people taking the tour.
It might not pass muster as being totally respectful to everyone, but I actually felt like they had one of the best recreations of what several events must have been like. There's a difference between reading a plaque with information and being shut in a room that is (safely) recreating the sounds and scents of the Great Fire.
One might be darker than the other, but that one also encouraged real empathy.
