The only thing is, Goku's just so peachy about the fact that his actions will in winning this tournament dome the trillions and trillions of lives in... seven... other universes (eight are entering, four are exempt, and one universe most likely will win unless ties are a thing? So maybe that numbers' right, I don't know). He's just acting like it's doesn't matter or that it's out of his control to stop so whatever. Which I guess is fair, but this is the same guy who summoned a universal spirit bomb to defeat kid Buu. So like he's a hero who can learn these techniques from the god/kais but also is so natural that he also jeopardizes lives. And also Gohan is seriously dropping the ball here in pestering his father. He's the good hearted son and is still cheering his father on in victory without even and comments to himself acknowledge his father has caused something tragic to happen soon because of his desire to fight.
Ultimately Goku's far from perfect, his training a key aspect in self improvement. And the Omni-King(s) decision(s) to eliminate losing universes was out of Goku's control. I know if Vegeta was at this exhibition map he would have ripped Goku a new one for putting several universes including his own at risk (especially Bra...), not caring that it was an accident or something Goku didn't know would happen. So I'm not really angry with Super's decision to through Goku into the villain limelight for a change acknowledging his character is ripe for this to happen, but some commentary on the magnitude of how serious this is from some people in universe 7 (besides Berus and the Kias) would be appreciated soon. I'm sure it's coming though.
