Mass death happens every second all around the world. Let's sit down and be sad. 
Argh the urge to be off-topic is too strong! *drowns in off-topicness*
Yes... but I do not see it happen. There is no sense in crying about it IRL, because I cannot stop the bombs from going off, the wars from starting, the murders from happening.
At least in that quest in DA:I, I could have stopped it. I could have prevented all of those villagers from dying, but I didn't. So it makes sense to be at least a little sad, considering you just condemned those innocents to die.
It may have been smarter to save the keep as opposed to a village, but that doesn't mean I cannot be a little saddened over the loss.
