Hey! I'm new here so I'll go anon, I hope you don't mind 👁️👄👁️ so I have this character, I'm still in the process of fleshing him out, and what I have of him is that he's a member of the army who lied in all of his psychological evaluations so he could get into the sniper team. Every time he shoots someone he Has to go and check if they're actually dead or at least shoot again, and if he doesn't he thinks they're not dead and are gonna come back for him. Is it considered OCD? Is it decent?
It’s definitely an unusual manifestation of OCD, and I don’t know if anyone IRL has ever experienced it, but I could potentially see that working for a fictional character!
The important thing here is that you shouldn’t just have them go check on the body once, or shoot the body again only once. OCD typically isn’t so easily reassured. He might feel like he has to check his victim’s vital signs over and over - what if his fingers weren’t in the right place to feel their pulse? What if their victim is holding their breath and is really good at playing dead?
He may also feel the compulsion to check on his victim a certain number of times before finally managing to force himself to move on - numbers can be very important in expressions of OCD.
You may also want to consider having other expressions of OCD in addition to checking the bodies. Check out my post here for some examples of what he might experience.
