Well trying not to relate to just the fire incident you mentioned but your question in general I would say there is a very alot of bad mixed in with the good. People have to be reasonable enough to expect the bad news to override the good news due to basic common sense. Seriously, if you were walking down an alley and on one side of you there was a dead body all bloodied up laying there but on the other side you were seeing a person giving a homeless man sitting there some money which do you think would grab your attention first? Of course people will always see the bad before the good, it’s a human instinct to do so and good lord I am very glad it is this way for very obvious reasons I shouldn’t even need to mention here. Ignoring the bad/evil can be a very dangerous habit.
People seeing the bad in something is showing compassion, I would question someone’s level of compassion if they were ignoring something very horrible happening to someone while pretending all is good or just focusing on their own immediate situation. It takes decent people to point out the bad to begin with, I’m glad it’s this way.
