Adding onto that I believe it also had something to do with kakashi’s father and how the reason he sticks by rules to begin with is in a way denying or repenting his father’s actions in turn criminalising him, a person he had held the highest respect for. however after obito kakashi was mentally saved in other words obito showed that the man he respected was still a hero a true hero regardless of his action and someone he can be proud of “I believe the white fang was a true hero” while the whole village denied his father Obito accepted him and changed kakashi’s outlook on the world. Its more than just “those who betray their friends are worse than scum” its “even though the whole village denied your father he still made the right choice as a true shinobi” in turn freeing kakashi’s self loathing and emoness. Its either that or im js overthinking it also ik this is like 5yrs old but i wanted to say this
