Rivals is literally canon and is Silver's introduction. It was never dubiously canon outside of western writers being confused. And about people "chasing", nothing shows Shadow changed between those two games.
Western writers made mistakes, because they rejected Silver's characterization in Japanese games like 06 and Rivals because they thought their version was better than Sega. Something you're doing right now. I am not "playing with extreme" I am telling you what Sega says in every profile. Here:

So tell me, how am I playing with "extremes" when I am literally saying what Sega intends for Shadow?
I am acting like my view is more valid because that's literally what Sega consistently says about their OWN character. Sega is the one saying everything I am saying, not me. The only egoist here is you, placing your own opinion above the creators of the character because you can't self-reflect and admit your interpretation of the character might be wrong. That the creators of the character are the one who don't understand him.
That's real egoism in my view.
