Think of a character, it could be your favorite or your least. It can be one of your own or any other in fiction(ex: Harry Potter, Black Widow, Nathan Drake, etc.). 

Take that character and kill them. Write the scene of how you want them to die, and if your character has already died, create a whole new scene of how you'd want them to die!

You can do whatever you'd like with this topic, whether it be grusome or not. 

Have fun, my friends! >:)
