I thought Daken's death was very apropos. This larger than life character with Machiavellian aspirations of power, held down and snuffed out in a inch deep puddle of dirty water like he was nothing. As great as he thought himself to be, he was taken out like a piece of gutter trash, and to add insult to injury we find out that for all his cunning and manipulation, he was nothing but a pawn being adeptly maneuvered behind the scene into this very outcome. It's mundane, but that's what makes it poetic.
Also on the issue of Sabretooth, if you remember back to the time of Identity Disc, Fury fully believed that Creed was the one pulling everyone's strings and manipulating the outcome. We of course know that isn't true, but Fury and Shield believed it, and it wasn't a hard sell. Wolverine has said in the past that Sabretooth plays the fool because it suits his needs and allows him to fly under the radar, in fact it's arguably that very character trait that allowed him to go over Daken like this in the first place, because very few people know Creed is capable of pulling it off. That's one of the things that makes him dangerous.
