Sure, but they have the one power, which explains how they were dug to even that depths AND in such perfect rectangles AND in such a perfect pattern. They could have dug them deeper with the power.
Not required, but far more likely than not. They were trying to get Logain to the tower as quickly as possible, and Logain's followers were still in the area. They wouldn't spend the many hours necessary to dig those shallow graves in frozen ground when they have the one power to do it very quickly.
When they pulled back the camera, we saw them all still lying there covered in blankets/sheets and nobody around.
The suicidal anger was the warders throwing themselves into battle after their Aes Sedai die, which this warder did. He just survived. Absent an enemy to throw himself against, moving on to just suicide seems like a natural progression. Remember, this was a supernatural effect that caused him to basically swallow her death and hold it inside of him. Even a warder could/would give in to that.
I understand. I’m just not sure what it added, rather than him just throw himself into battle. The writers instead chose a protracted, drawn out conclusion to it. Not sure when clearly dozens of people died based on the graves at the start Steppans funeral led to such an exaggerated outpouring of grief. It added very little to my mind.
I mean, I can see that they are setting up and foreshadowing certain future events for Lan and Moiraine, but, yes, I agree it went on a bit too much. They should have at least shortened it up enough to actually give us the scene of Loial meeting Nynaeve in the Tower gardens.
Darkfriends are an interesting lot in the books. For a long time, they were a secret cabal devoted to the Dark One (who they call the Great Lord of the Dark but who is a Satan stand-in) and organized into a cross between a cult and a gang. As the events of the book begin to unfold, however, the prison that has held the Dark One away from the world is weakening, and some of his very powerful lieutenants have gotten out or are able to reach into the world again (the Dark One and his Forsaken (the lieutenants) were sealed away by the last Dragon). The darkfriends in the books are routinely people who thought they were getting in with a club of people to get ahead in the world but are finding out that their oaths have serious teeth now that the Forsaken are loose again. In the books, the darkfriends after Rand and Co are directed by their own leaders and the Myrdraal, not driven by dreams. However, as more Forsaken are loosed, many have abilities to affect the dreams and even utilize an entire dreamworld and this becomes more common. It appears they smashed this into the earlier episodes.
