Kanye West I'm Gonna Help Dads Feed Their Kids

Kanye West is raging and ranting -- when he's on Twitter -- but in the real world the guy's acting like he's on a campaign to win a Nobel Peace Prize.

Kind Kanye's latest beneficiaries were a group of patient fans waiting for him outside his NYC pad ... and even the paparazzi who hung out for him. 

Check out the vid -- at first he looks like he's gonna blow off everyone, not saying a word. And then he drops a very huge ... very valuable surprise for the fans. He wasn't done there. When he and Kim Kardashian return from dinner, you gotta see his chat with the photogs.

This is Yeezy ... the "It's a Wonderful Life" edition -- and almost enough to make people forget about that Bill Cosby thing.
