That awks moment where he admits that Genocide was planning to make a move on the 303, but then gets salty that the 303 didn't back him up when they got slaughtered. Do you see the problem with that?

But overall, when all else fails, blame the 303. It's the only thing you peasants are good at. 

While I do also think it is interesting that he would be upset over this, as I stated, I do also think he deserves a chance to explain whether or not his father had proof of an attack by the 303. If so, it would be a different situation. Although, it would still seem weird to be so upset by the supposed betrayal, but for completely different reasons. 

I havent seen Genocide bitching about anything since his demise, how can you say he was salty about it?
he came across as very humble in his fairwell speech.

Sonya, I am not sure to whom you are referring, I do believe most, if not all comments, have been directed to Johnny Bravo Jr.
