I think the ones who are taking Uvo's death hard are the original members that are still alive. The ones who got in by killing another member are probably wondering what all the whining is about at this point. Goes to show you can swear to a life of chaos but it's hard when it effects you personally.
How many first time viewers actually thought there was going to be some kind of Nobunaga vs Killua+/Gon fight there? Just curious.
