Sasuke, when not a victim to darkness, has a heart of gold.
Throughout Part I, despite his aloof facade, it's always Sasuke who cares the most about his friends. It's always Sasuke who's looking out for them and sacrificing himself and protecting them.
Hell, it's Sasuke who cares about them and looks after them emotionally too. Who motivated Sakura during CE? Who went out of his way to encourage Naruto, knowing exactly what to say? Naruto was often oblivious.
It's blatant to the point that Naruto realized the power of friendship AFTER Sasuke offered to sacrifice himself for Sakura vs Gaara
There's a reason why both Naruto and Sakura were desperate to get Sasuke back. He was just that caring a friend to them
He'd obviously try his best to save Naruto if situations were reversed and he never fell to darkness. But that's not how Indra curse works ig
But Sasuke is also a realist. He'd probably resolve into killing Naruto as necessity if need be rather than being hopeless romantic about it
