Maybe that is why Karin does not recognize his chakra, plus he might not like the way his bloodline is going to go down in history plus using his father's power to achieve what they are doing and goes against his father's uktimate wish was for peace to be achieved. But then I wonder where his younger brother is if it is the eldest son of The sage of the Six Paths. By everything I've read about them he was pretty strong even if he not receive his father's blessing. With only 2 uchiha remaining sasuke is by far the less evil of the 2 ☺
Could be thinking too much too ☺
