OC ideas that y'all can use

A Sociopath

Imagine, a Sociopathic OC

Ever since they turned 4, they seemed to hate everything. They refused to do anything that was asked of them. They would randomly get angry and start throwing things at people. It appeared to be a behavioral issue until every attempt for treatment failed.

A completely amoral person.

First, when they were 5, they killed an innocent animal with no sign of remorse.

When they were 7, they tried to set fire to their house, simply because they didn't like the color of the walls. They got expelled from school because they brought an airgun and attempted to shoot their teacher because she was fat and they didn't like fat people. 

Later, they tried to bury their baby brother/sister alive beause the crying annoyed them.

At the age of 17, they robbed a bank and pretended to be insane in court. But they faked insanity too well. They were sent to an insane asylum, where they lived for 11 years and eventually died.

How's this? I had fun writing this! I hope you can have as much fun with it as I did!
