This is a terrible way of reacting to a tragedy like this one. How would you feel if someone answered like that for a similar event in your country? For me It doesn't matter if it's here or anywhere else, when you hear about something like this you can't laugh about it. Imagine if your family & friends were involved in it, always put yourself in other peoples' situations, it will open your mind.
On topic, I think it is absurd that in 2018, such stupidity can exist, there were many people that didn't even know where the fire was or even if there was a fire, and they were staying inside their houses till the last moment. The local authorities are responsible for not informing them to go away to the shore. It's also ridiculous how people can drown, flip their boat over, and not being able to stay afloat. And of course the ones that put the fire, every year it's the same here, usually they have something to gain, like space to erect buildings where it was not legal before. They should die a slow and painful death.
