You could add:
- Glibness/superficial charm: Just look at his vocal fanclub if you don't believe he can be charming.
- Grandiose sense of self-worth: still views himself as a daring rogue who's the best hope to restore his people to greatness even though he's the one who destroyed their civilization in the first place
- Lack of remorse or guilt: Although he (claims to) feel guilt about what's he's about to do, he's remarkably good at compartmentalizing.
- Callous/lack of empathy: Took him time to realize that non mages were still sentient creatures
- Failure to accept responsibility for own actions: Destroyed the Elvhen civilization, views himself as the best hope to restoring it regardless
- Lack of realistic, long-term goals: resurrecting an empire dead for millennia and forgotten by most? About to free the very despots he imprisoned?
- Early behavioral problems/Juvenile delinquency: Admit to have been a lot more aggressive and cocky during his youth, plus the whole "destroyed my civilization to avenge my mentor/mother-figure" thing
- Criminal versatility: reckless disregard who the safety of others: pretty much summarizes his master plan.
- Many short-term marital relationships: Hellooooooo Inquisitor Lavellan
- Promiscuous sexual behavior: better leave that to the realm of headcanons
1: is wrong. His 'army' of fans like him because the character has tons of depth, loads of emotion, is a bit of a conflicted/tortured soul and, er, because he's quite fit. 'Superficial charm' isn't anywhere on the list of why people like him. He's not good at making friends.
3. is wrong. He feels remorse, he just doesn't let it stop him. Different things.
4. is wrong. If he's a friend/romanced, he freely admits that he was incorrect. The fact that he can learn to see people differently means he can't be a psychopath because this isn't something that psychopaths are typically capable of doing.
5. is wrong. The stinger at the end of DAI has him say to Mythal 'It's my fault, I should pay the price, but the People need me'. He's fully intending to pay the price when he's done what he thinks he needs to do.
7. Applies to the vast majority of young men (not 'juvenile delinquency' per se, but certainly a tendency to be a bit hot-blooded) . If you're claiming that being 'hot blooded and cocky' is a sign of being a psychopath then I guess most young men in the world are too. In fact, being a bit reckless is a thing many young (and not so young) people do regardless of gender
Also, he'd hardly be the first non-psychopath to commit crimes to avenge someone they love. The very fact that he loved Mythal enough to avenge her, indicates that he is not a psycho, but a man whose emotions can get the better of him.
9. One relationship is 'many'?
10. (Limited) Evidence suggests otherwise.
2, 6 and 8 you can have I guess, although with 6) I would question whether his plan is 'unrealistic' - given the amount of power he has now, it seems pretty plausible to me ...
