I dunno. Oro is wayyyyy to nice to Sasuke. Like Sasuke would fall for people being nice and friendly to him. He learned enough to not trust him at all. Before, Oro wanted to kill Sasuke for the eyes and now he says stuff like 'I'm with this boy' like he is his uncle or something. That's a bad sign. No one should fall for this Oro-good boy stuff. He wants to clear the battlefield and get rid of the other baddies to have some free space for his own plans. That's probably all.
Sasuke's father loved his son. He just couldn't show it. Typical clan royalty problem I think. See Hinata's father, he is even worse. These people probably believe it's the best for a child to be strong and not learn love. It's wrong under normal circumstances, but with their constant wars it's probably understandable that they are rough like that.
