It was evident that Orochimaru was good at a younger age, but even Hiruzen notes that he saw darkness in him.
I doubt it was because Minato was selected for Hokage over him, but that may have been the reason. I think Jiraiya thought that's why he defected.
Is it possible he ended up like Sauce where Konoha was responsible for his parent's death?
Hopefully this will be addressed after the war, when we get the exposition and closure on the rest of the characters.
Should point out that there was a chopped out flashback of EMS Sasuke calling Orochimaru out about claiming he "attacked the Leaf on a whim" then followed up with questioning why he did it.
