He's won, you've lost. When he thinks back to that Stoke game, he laughs. When he looks at the league table, he laughs. The media are on his side. Fans of other clubs are on his side. He doesn't care if Newcastle fans hate him. Even if it goes terribly next season, people will refer back to the 'good job' he did at Newcastle, and his first one and a half seasons at Palace.
Then he'll get another PL job somewhere, or a cushy job as a media expert. Or maybe just retire on his millions and focus on his playboy lifestyle. His ego will not be dented.
Accept it, move on. It's over. Will be less painful for you this way.
