Maybe it's just because in this "side" things show different... but what are those horrible deeds of the sociatel everybody mentions? As I see it, they just defend themselves... ›››
Some players mistakenly think that the Scoia'tael kills everyone in the bank during the bank job. Actually, those people lying on the ground are NOT dead, as players will discover if they try to talk to them. And since the bank was Vivaldi's to begin with, the Scoia'tael are only stealing BACK what belonged to a dwarf to begin with. But players who see bodies on the ground and believe them to be dead are understandably upset at what they think is murder.
In several runs thorough the game, I've never sided with the Order; I've only taken the Scoia'tael or neutral paths. But you can do a task for Siegfried in Chapter 3 -- if you do it before the bank job happens -- that shows a darker side of the Scoia'tael.
Siegfried tells you that people have gone missing in the cemetery and asks you to check it out. When you enter the cemetery, you see a ghoul feasting on a human corpse. Ah, there's the problem, right? Actually, no. If you talk to the ghoul (this is an unusual ghoul, one who can talk), he tells you that actually, it's a Scoia'tael unit that's been killing people in the cemetery, and he tells you where to find them.
If you go there, you find a group of elves and dwarves who tell you that you don't have time to fight them, because they've just pushed a group of humans into the crypt that you're all standing next to. If you enter the crypt, you can save SOME of the humans but not all of them. This particular Scoia'tael unit appears to be killing any humans they can get their hands on, regardless of whether or not those humans have ever done anything to elves and dwarves. They've gone from fighting for their rights to a race war.
I agree with you in that I think the Scoia'tael's cause is more just than the Order's. But there are a lot of people in the Scoia'tael, Yaevinn doesn't have control over all of them, and some of them do use unsavory methods. But find an army where no one ever does anything bad -- it can't be done.
