I think there won't be any more chapters out. Will have to wait for the book, sadly (though to be honest, we have already gotten quite a bit of it in a preview, hehe)

Probably said something along the lines of Dalinar wasting a shardplate on a cripple to her friends, thinking not a big deal... Would fit nicely with Adolin giving Renarin the Blade he gained in the duel as well

I think that Amaram is weak, meaning he doesn't know what is right and wrong. Alethi way is to be ruthless, as they think a perfect soldier should be. That act was very like that. On other hand Amaram was guided by Gavilar, who, in recent years before he was killed, liked the old way, honorable ways, so Amaram is(or at least, was) not sure what is the right thing to do at the time. He also thinks that Darkeyes are inferior to Lighteyes (i mean, he believes that the way he thinks that water is wet, there is no doubt in his mind about that), so he got convinced that its the right thing to do (can't have those incompetent little darkeyes soldier have a Blade and Plate, now can we? They might hurt themselves with it ). Amaram feels that he should be honorable because of Gavilar, not because he really belives in honor. For example, Dalinar really craved Navani and his brother's throne. Instead of taking it, he promised himself that he will never, ever take it. Amaram isn't a bad person. He just can't know what is the right and wrong thing to do, so he needs to have someone whom he respects to tell him what is right and wrong. Amaram is a soldier, not a leader, sadly. Dalinar on the other hand has no problem knowing what is right and what is wrong Also, since someone brought up terrorist and the word cowardly in same line, I think that pershaps you should read Alamut by Vladimir Bartol. It will certanly give you an interesting view of that sad act. I think that there are two main reason for this. Either hate or manipulation from another person. Regardless, if you don't feel like reading it,a summary is a good way to give you something to think about it http://en.wikipedia.org/wiki/Alamut_(1938_novel)

There are two points that I think you should be aware of. Brandon Sanderson said something along the lines of (no I don't know where, picked up the link on this forum some time ago, though ) that Shard Blades are different. So Szeth's Blade and the Blade that Shallan's brother had when Kaladin killed him were different. I think that Szeth's Blade gives the ability to surgebind to him, while others do not. Not sure if Brandon only implied this or confirmed, though, you'll have to find that on your own, if you want to Another point is that Szeth's eye colour changes when he summons his Blade. It changes to light green, i think. Its somewhere in the first book. I don't think all Blades change the wielder's eye colour, though. So, no, I don't think that eye colour has any importance regarding one's abilites or class of Surgebinding. I think that the only difference that eye colour makes is by how people are percivied with different eye colour.
