To me at least they pretty clearly laid out Hydealyn as, well, not exactly being good. I get that she was definitely portrayed more "good" than some people liked but it never really felt to me like the game handwaved what she did (and the exact why is always going to be up for debate, just as it was on the other side).

To be honest, though, I actually don't see what they did as being safe. In fact, given all of the hints we had going in to EW, I actually feel making Hydealyn straight up "the bad guy" would have been the safer and more predictable route. So many people were predicting that "twist" that it really wouldn't have been much of a twist at all.
