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?"
Point taken. I'm guessing that when Ady gets to Episode 3, one of his plans is removing all dialogue from Ani/Obi duel, so there won't be any, "From my point of view, the Jedi are evil."
The best way I can think of having Anakin be noble without Ady having to do too much work on ROTS is to have the Trade Federation plan to barricade Coruscant as a last ditch effort to take over the galaxy and Anakin goes to wipe out the Trade Federation in order to prevent that from happening. He knows the Viceroy would always be well guarded or have an escape plan, so Anakin is willing to destroy himself along with the Separatists leaders and their base to ensure the safety of the Republic and the rest of the Galaxy.
It would be kinda like how Luke destroyed the Death Star and even though he killed hundreds (if not thousands) of Imperial officers and possibly more Rebels being held prisoner, he ended up saving infinitely innocent wildlife on Yavin 4 as well as other planets in the Galaxy from suffering the same fate as Alderaan.
If that's a bad example, then I apologize for it.
