Will my Tav have a bit of a positive influence on some companions
I for one hope that IF we will have good influence and get some redemption arcs, we will also get some options to use our bad influence and have some corruption arcs aswell.
Yes, I would very much like that, too, I forgot to include this in my post. It should be possible in both directions.
I think from what we already know of our companions, there is some point in every character's story/characterization that would allow for them to be swayed a bit in one direction or another.
I think there are already some examples where companions do something that would maybe not fit our first impression of them, because there is something that is even more important to them, so that they might act contrary to their own convictions to achieve this.
Gale is the only one who does not approve if we reject Raphael's offer, because he is very (or a bit over-) confident that he can outsmart him. I think his primary goal is to find a solution for his magical bomb problem, and though his intentions are good, I wonder what he might do for it. His flaw might be that he is a bit too confident in himself.
When Spike promises Wyll to tell him where Mizora is if he tortures a man, Wyll would very reluctantly do so, because he desperately wants to get out of the pact.
Personally, I think that alignment maybe does not play the most important role in BG3, I think that the characters act according to their traits, ideals, bonds and flaws, and their backgrounds (like the character creation in the 5e Player's Handbook).
"Evil" companions might agree or be indifferent to something that would be considered "good", when it corresponds with their own goals. I think they do not choose one option just because it is the "evil" option.
I like that, I think this way, it makes for more interesting and nuanced characters.
Personally, I am very fine without the assignment of alignment. It does make sense e.g. for devils or demons, because they are the embodiment of evil, but I think that for "normal" characters, the characterization via traits, bonds, ideals and flaws works better.
