Well, I guess OP has a point.
Fenris was pretty messed up, that's true. And he was forced to kill his friends, Fog Warriors, when his master demanded it, and there have probably been other events like that, including sexual abuse, total memory loss, lyrium branded into his body, and just general ripping-people's-hearts-out.
Merrill might be adorable, but she's a blood mage who had relations and pacts with a demon, which is, well, crazy for 99% people in southern Thedas, including her own clan.
Zevran killed multiple people, slept with multple people and then killed them, then slept with multiple people to get close to other people and then to kill them, and, well, it's still his modus operandi. I'd say it's absolutely and completely messed up. At least Leliana can find redemption. Zevran cheerfully goes around his business to find more people, sleep with them and then, well, kill them.
Sera is crazy. And proud of it.
Velanna was very crazy. She might've calmed down a little, but when she meet her? Oh yes.
Solas... well, actually, yes, he is as close to normal as is possible for an ancient elven god, but you know what? Being an ancient elven god is not normal.
Good news is, there're pretty few well-adjusted non-elven characters around, anyway. There's Cassandra, there's Josephine, Aveline - and I'm already struggling to add someone else who is not Scout Harding. So, elf or no, nearly everyone is messed up, and cheers to that.
