How much do you think Inuyasha changed in The Final Act?

i think its more like:
Before-
"F*** Kagome, I dont give a d*** about that b****, all she's good for is detecting those f****** shards!"
After-
" Kagome taught me how to smile, how to believe in people, Kagome was the reason I could make friends and rely on those friends, To shed tears for others, to understand true strength and kindness…They’re all things I learned from Kagome. Kagome was born to meet me and I was born for her."
