Whatever the consequence, I hope it's better implemented than the DA2 rivalry/friendship system in which everything was extremes. If on friendship path, they assume we agree on everything and vice versa for rivalry. Leaving aside a few major impacts, by and large what Hawke did or didn't do seemed to have little effect on the companions. Now in Origins, I understood when Alistair hung around even if you act despicably at least till the landsmeet because he sees the bigger picture and puts aside his differences with the warden to kill the archdemon. In DA2, however, it made no sense sometimes. There's not too much holding many of the companions to Hawke, there's no bigger purpose in comparison to the blight and yet everything appeared fine and dandy if Hawke acts like a total ass.
I'm not saying good aligned characters should always object strongly and leave when a PC makes such decisions. I just want some consequence to those actions beyond a short back and forth showing there is disagreement for the moment and once that's done everything is once again back to normal. I think the devs have said your decisions will have a lasting impact on how your companions react, would be nice to see how well that's implemented. I'm hopeful and believe they have a better system in place than DA2.
