They aren't as much of a character as the daemonhost, but they are flaws. I don't see how it's a problem if you play them yourself most of the time, but godfang should be able to use them too if he wants them to be a plot device or have them actually hinder you in some way. You have both hellbound and haunted though, which is extra bad, since hellbound is already haunted+.
The Daemonhost actually has stats and can take control of Amy. It's a tiny bit better at it than she is too, since it can freely regain control if it relinquished it in the first place and Amy has to fight to get it back every time she loses control like if she say, goes to sleep. So it's definitely more of a character.
