Again, he heard the children singing a nursery rhyme. He needed a second, literally one second, to scream "Stop!" to his men and the attack would stop. He could even tell his soldiers later that they had bad intel after falling back. But he keeps the attack going.
Still stinks that we can't stop the Game from existing in DAI.
I am being realistic. I see him as a captain of the Orlesian military, which he was. Thus he was a soldier whose job is to protect the people of Orlais, not slaughter them.
We really don't know anything about the chevalier that almost patroned Blackwall. For all we know, he was as bad as the rest of them. He was at the very least a murderer since the Chevalier initiation involves killing City Elves.
As for romance content, can't comment.
He could call a retreat. And it only takes one second to do so.
Well, he said he was told it was just the target and bodyguards, so he could say "We got bad intel" to his troops. He isn't lying.
As others said, from how other companions describe what he does, it is creepy.
He would have been more interesting if he actually did call the attack back, since he is a soldier going against the Game, in my opinion.
I have one word for you: fear.
Have you never experienced a moment of paralytic fear in your life? Because I have - I'm an excellent writer, but I hate public speaking and outright fear it. That's why I occasionally ended up completely freezing just when having to stand up to give presentation in front of the rest of the class in the distant past. One time, it was so horribly bad that I couldn't raise my hand and ask a question of a subject who was there for us to interview (it was a journalism class, FYI).
Now just think about that, and then try to consider how much worse it is if you're faced with a major life-and-death situation. I think you might just freeze for long enough that the opportunity to take action passes you by. I believe that even a big, strapping man can experience that level of fear in certain situations. And with regards to the chevaliers, yeah, Orlesian culture can be crappy, but don't you understand what the chevalier was doing and what he was sacrificing for Rainier?
Ignoring their initiation rites (deplorable, of course), the old chevalier was clearly a man who did have a good heart. You don't give up the kind of gold or the fame that he did for no reason. Yet the old chevalier did this because he saw something in Rainier. if the chevalier were just some sort of selfish git, then he didn't have to help Rainier at all.
And I would now like to point out that samurai sometimes tested their swords on actual people, so are you going to cast aspersions on every single one of them? I just think this shows that a warrior class - fictional or real - can be the embodiment of honor, yet still engage in completely crappy behavior that is somehow acceptable within their own society.
Oh, and as for his stopping making him more interesting? The only thing stopping the murders would have accomplished is ensuring that Rainier was dead and not in DA:I. I'm not sure how that works out to being more interesting when he wouldn't be there to tell you his tale.
