When did you realize Tony is a good person?

I guess it's kind of obvious Tony is a great person from the get go but he hadn't done anything I had personally considered admirable for most of the show, I think the only little nice thing that almost drove me over was when he killed Ralph but even then I wasn't completely sold on the whole Tony is completely good thing. I just watched Tony but his family onion rings and it honestly looked tasty I think. After this it's hard for me to look at Tony and have any type of hatred for him even as AJ goes into depression I can't help but feel bad the fact that somehow Tony is getting something he doesn’t deserve. Besides this I just really wonder how it took so long for me to catch on to how much of a wonderful person Tony is. Also I'd interested if the Christopher situation is the straw that broke other camels backs or was I really that late to the party?
