I don't find the reason for killing Anders and his team compelling, ethically speaking. We learn from the dead man that they formed a pact with Zariel. But if we were to kill anyone who has formed pacts with beings from the Hells, then we should strike Wyll dead too. You might say that Wyll is trying to do good with his powers. But so are Anders and his team. They were killing gnolls while in pursuit of Karlach.
They deceived the player character that they were paladins, but Anders seemed to genuinely believe that Karlach was dangerous, as even after confessing the truth of their pact with Zariel to you and you told them you would not help them kill Karlach, Anders accepted your decision and asked you to be careful with Karlach nonetheless.
They mislead the player about their identity, and then sent to kill that tiefling without any proof: it's his word vs. her word, and after this is started, we can get proof that he is lying, while she still can be innocent (or not, that will be revealed by the story past early access). They are
fallen Paladins, and the explanation given when asked why they accepted the offer of the demon was that their own God wasn't answering in the way they wanted
They have no honor. No matter the reasons. They aren't doing good, killing the gnolls is just self-defense. They obviously following the orders of someone who can't be called good at all, and they have no excuses considering their past.
We can know more about her
with the help of tadpole, so at least part of what she says is true, unless the tadpole leads us into believing an alternate reality
I have no doubts at all: will just treat them as bandits, they are even more dangerous than that, and kill them every time. It's full black, not even gray, despite their excuses.
Not sure about her yet, but so far she seems nice. Kind of a Gale person, just she reveals some of her secrets before joining us, unlike the wizard.
Edit: Wyl told me nothing so far about him (and I finished whole early access and cleared 100%), but he isn't in the party, never was, and that could be the reason. He doesn't talk much in the camp and I don't ask much. He is weird and I trust Shadowheart more than Wyl (not that I can really trust Shadowheart). My party is Lae, Gale, Shadowheart. Wyl and a few others are camp residents. Astarion was killed when he was crying on the road "help, I need help" (a nice sneaky backstab did it, oh well, he asked for help, and this comes from a 100% good character, as that Mandalorian character would say: "I have spoken")
