By comparison Logan looks like a choirboy ... maybe that's what Marvel is going for. Kinda of like Venom Spider and Azrael Batman, readers are given a more extreme - and distasteful - version of the character in order to make them like/appreciate the original better. Of course on the other end you have X-23 who is clearly the best of the bunch (IMO).
Is there a particular reason Daken arranged to have his bed buddy offed? Other than just to see if he could?
