I'm aware of how history has a tendency to rhyme with itself. Between stories shared in this subreddit, secondhand dramas I've witnessed over the years, and a few thankfully-less-serious events within my own childhood, I've come to the quaint conclusion that some people just shouldn't be parents.

What can any person do -- trauma victim or otherwise -- to better and more ethically center one's own possible child-rearing plans and actions? I'm willing to bet that if any time traveler had ever gone back to tell current-jerkface-parents that they would eventually become a jerkface-parent, most or all recipients of such news would likely scoff at it with the understandable (if frustrating) mentality of "that will never be me."

Well, I haven't been visited by time travelers from the future, but many travelers from the past are here in this very subreddit. How do I find out if this ever MIGHT happen to me? (Or worse, how do I find out if a potential co-parent might be a future-jerkface?) Edit: I'm also worried that some future-jerkface-parents might -- prior to having kids -- be a non-jerkface, making the future-JFPs more difficult to spot, particularly in the case of identifying someone now in my love life with whom children might be a future possibility.
