The only possible reason i see of Sasuke's behaviour over Sarada is that he thought she was an ally of Shin due her Sharingan.

Let's think about it, even if Sarada is an Uchiha, Sasuke wouldn't expect her to awake the sharingan at that age, and in that TIME. Long story short he thought that "Well My Daughter has been raised by his mother, she has been threated well, she lives in a pacific world where wars are over and she is a totally normal girl without any pain that can trigger sharingan event, so this girl with Sharingan is not my daughter".

Case closed.
