Yeah, that makes sense. I've been trying to tell myself something similar regarding my characters as well when it comes to writing. That They're not real, and they're separate fictional entities from me. To quote a writing friend of mine a while back, "Those characters don't make you who you are. You make them who they are, And if they (Your characters) disappoint, you replace them. No matter what those characters are to you, You will make more, And one day you will have to move on from them. So just do your best, or don't do it at all."

Yeah, that's what I was thinking as well. Or making them historical characters in universe like what my aforementioned writing friend did with characters from previous versions of his stories that weren't clicking with him that much.
