Should movies on real life tragedies be made?

This is the thought which came to my mind while watching Hotel Mumbai. Why should we make or watch movies based on someone's tragedies? Isn't that ethically wrong? Someone died and their families suffered. And we are watching that on screen munching our 🍿 and drinking coke. How can a real life tragedy be entertainment for us? How would the people who suffered in these disasters would feel? Ever thought of that?

Edit : I'm on 15 posts limit so can't waste it. Just want to tell that by real life tragedies I mean real life incidents. Movies on rape, murder or any other crime can still be made but making movies fictionalized movies on real life incidents? Is it right or morally correct?

Art is not merely for entertainment. Art can be for analysis. Art can be for education. Art cake be for social change. Art can be for art's sake.

I haven't watched Hotel Mumbai, but from reviews it appears the makers have done a good job of treating the matter with all the seriousness it calls for.

If we banned all art based on real life tragedies, there would be none made on casteism. None on rape. None on murder of the underprivileged. None on the financial shenanigans which left millions bankrupt.
