So yeath its probably a part of schizophrenia or harm ocd.

I dont see a need to worry. Because logically u know, u dont have a reason to do smth like that and it will have consequences. I know it might be a little disturbing, but having some thoughts or ideations doesnt mean you will act out on it.

And I see you dont want to have these thoughts/ideations, so it doesnt sound as a person who's gonna do smth, that doesnt want to.

Dont try to fight these thoughts, because it can intensify them. Just let them flow thru you with knowing that they are illogical and you dont have a need to smth like that. With time they might disappear.
