Lot of "cruel" examples here and alot of examples of standing by what you believe for both sides, take the Bethany being killed by Meredith, thats not evil, bethany decides to side with the mages hawke think's she is wrong, if it was anyone outwith her being a relation would it be a "evil" thing? no it wouldnt, only time i sided with templars with bethany alive though was her as a grey warden so i dont know the choices you have in game there, but im guessing the choices are side with her or continue siding with templars, for me a 3rd choice should be present, knock her the frack out an deal with her later (in a argument sense)
I've yet to encounter "evil" choices in any Bioware game tbh, being a dick yeah there plenty of them, but evil no.
I'm doing a few more play throughs of DA2 though will need to do one where it puts me in the position with meredith an Bethany see how it plays out an what choices are available, but as i said in that scene if it just 2 choices you have then for me it just an example of the game being a dick an not evil
