Okay so I have a character who has the disorder (i've heard little about it) and I want to know how to write a character who has the disorder (I don't want to degrade someone or paint people who have the disorder as monsters and want to get as much information as I can to do it right)
I surprisingly don't know anyone with ASPD, but! As a future psychologist (fingers crossed) I do know some stuff from violent studying at 3 am!!
Here: a website that I trust https://www.psychologytoday.com/us/conditions/antisocial-personality-disorder it goes over all the basics, reading this and maybe a few other articles will help you for sure
I wouldn't really paint your character as a monster. They can be cool and charming. They just don't give a shit about you and wouldn't mind doing anything bad to you if it helped them.
Hope this helps uwu
Thank you so much :D))
