Some of it could have been, but it was mainly damage from the assault that still persists today. Demonic possession mainly consists of inserted thoughts. A twisted psyche is much worse and can be caused by spiritual assault very easily.

Try trauma release exercises (TRE). Do you know if it's possible for a cursed image to open up the viewer for a demon to possess them?

Yeah and there is more than one form of possession the Catholics have an extensive manual on it. I would recommend using a priest if you need it. There is other ways, but they have it down to a science.
