It's not about what he says, but how he says it. Pardon me, but jedi or not, he is still a person, and he is attached to his daughter. It's pretty obvious from how he speaks about her being in danger before they send you to that ship. Besides, this particular jedi was shown to be... not "by the book" one, to say the least. So no, I don't find his replay fine.
being a person doesnt require to be emotional. maybe he "loved" her but what made him a good jedi is how he reacted after her death.
