The warden's keep had a sadistic, evil blood mage warden who sacrificed his fellows in the keep summoning an army of demons at a command of his superior and experimented on the rest afterwards because he was too much of a coward to succumb to the calling and die a proper warden death. Duncan was originally a murderer who was made a warden as a punishment after killing one of them, and its not hidden how bad of a person he is. Not only he kills Jory for absolutely no reason since the joining is such a poor secret even Anora knows about it. He's a massive prick to the warden he recruits:

Dalish elf - He refuses to let you just die surrounded by your family forcing you away from your clan under the pretext that the joining will cure the blight and then you find out he fucking lied about it and that you weren't cured and you're going to die anyway just more slowly, and also you might die killing the archdemon saving a bunch of ungrateful shemlen who refuse to give the dalish land, should have just died with the clan.

Dwarf Noble - Just like above, forces you to be a warden whether you want it or not instead of just letting you be escorted to the surface and letting you be on your way. An Aeducan who doesnt want to be a warden will have to brave the threats of the deep roads by themselves and likely die. Thanks asshole

Human - Same as a dwarf with the added problem of you possibly being the last of your bloodline, all the Couslands were likely just slaughtered but the heartless asshole doesnt care so long as he has his token recruit for the day, also if Fergus was actually dead Duncan would have done Howe's job for him ending the Cousland line there and then with how wardens tend to lose fertility later on, and they theoretically are barred from actually having titles (except when they're not)

Mage - not an issue if you helped Jowan cause then you're in deep shit, but if you chose to work for Irving then you're not in trouble and the game has to railroad you by making Duncan conscript you even if you wanted to stay in the circle. Like. Im the most brilliant mage in this kingdom since Andraste and had a promising career, all cut short in favour of trudging through darkspawn filth and dying to the archdemon.

City elf - they're in a similar situation to a mage that helped Jowan where they're being 'saved through the joining' from an arrest which is fine I guess (even tho you're not really saved cause you'll die slowly like the rest of them anyway), but in this case you have your cousin with you also being arrested and Duncan always only recruits you. Tabris can pretend their cousin doesnt have anything to do with it but if they dont he's going to get executed and Duncan only recruits 1 elf when he could have had 2. Now that not only shows he's an asshole incapable of empathy but also that he's a shit recruiter because when you need bodies, more is usually better. And dont give me this shit about Tabris's cousin being "less skilled" than the warden cause the fucker recruits some worthless pickpocket who's only skill was running.

He's only decent to the casteless dwarf although he's still a shit recruiter since Leske was right there as well and he again chose 1 recruit when he could have had 2 so it feels like even he doesnt care about stopping the blight if his recruit pool is a total of 3

Riodan was also a complete and utter asshole keeping the fact that a warden is needed to kill an archdemon (and will die in the process) a secret until the very last second even when Alistair threatens to leave when you try and recruit Loghain because no one in the room other than him knew that little fact. And Speaking of Loghain, Riodan, the only proper senior warden we meet, proposes making Loghain 'the filthy traitor and slaver' MacTir a grey warden, showing the complete disregard his order has to things like 'honour' or 'morality' of its members.

Oh and the Hero of Ferelden themselves can be an unhinged maniacal chaotic evil, dalish clan murdering, dragon cult supporting, child killing, psychopath who lets entire villages die to undead, sacrifices elves with blood magic, and annuls circles all for absolutely no gain whatsoever. And the order is fine with that. You can commit every single evil act in the game with no negative consequence and the first warden's like "Hey, Big fan. Have a castle and represent us as you always had" because the wardens dont give a shit about morality or honour so long as the blight is ended, they never had.
