Like if he's there to avenge Padme for four years earlier when Viceroy Gunray put out a hit on his wife?

The avenge angle is still a personal vendetta, and something a Jedi wouldn't do. I can't imagine Yoda from ESB hunting someone down to chop their head off for a wrong they did to him years before.

I interpret Bingo's suggestion to mean that Anakin hasn't turned yet, he's this great hero that everybody loves, and he knows he going into something dangerous from which he might not return. He would be telling Padme, "I'm doing this because if I succeed it will help everyone, and Palpatine says nobody can do it but me. I might not make it back, but I want you to know that I love you and if I die, our son can carry on in my place one day."

It's noble and admirable - sacrificing himself for the fate of so many others, instead of "I'm gonna go kill all the guys me and my new boss are mad at. Because I'm the bad guy now. See? I have yellow eyes and my scowl is deeper than before. I'm the bad guy. Watch me kill everybody. Did you pick up on the fact that I'm now the bad guy?"
