Eren still blames him for that. Remember that conversation in chapter 46 when he was asking him what he was thinking when he told them about his mother's death and culminated with "I make sure that you two die the most painful death possible"?

Also, it seems that despite that, they felt somewhat shocked as they were seeing him get eaten, but I don't think they felt as bad as when Connie and Sasha cried when they thought they had killed Reiner, because Reiner was always like a big brother to them while Bertolt was mostly on the background.
