Right after Spopovich got up from getting his neck snapped and letting fixed it, she should've ran off the stage and give up.

And let's be real here, NOBODY WOULD BLAME HER! Even if she's Herc's daughter, after what Spopovich did, absolutely no one, not a single soul in that audience would blame her for giving up.

that is valid

she had so many chances to literally give up against Spopovich but no, her doing this is what leads to Gohan getting his energy stolen by Spopovich and Co. If she had just decided to give up against Spopovich, Gohan wouldn't get pissed off about Spopovich beating the crap out of her and that wouldn't lead to his energy getting stolen. Indirect or not it's still dumb regardless

she could have just decided to give up against him.

Spopovich's only mistake was fighting back.

The whole fight with Spopovich was fine and slightly reasonable, it's only after he got back up from something you should not have gotten back up from, it where she messed up.

and as for Vegeta letting himself get possessed. that's not just dumb but petty too. keep in mind he killed loads of people just to spite Goku into fighting him.

and he intentionally let himself get possessed leading to Buu getting released.

^^yeah Videl messed up the moment she tried to snap Spopovich's neck. She's lucky Spopovich didn't die from that due to the Majin Magic. Why did she even try to kill him?

It was more of accident on her part, she genuinely wasn't trying to kill him, and him dying to that was honestly the best outcome.

Because A: As we clearly saw, she would've been disqualified anyways. B: That's already one minion down for Babidi, and C: More of a chance for Yamu to leave and the Kais and fighters to follow him.

^good point

I'd say Vegeta letting himself get possessed is the most dumb; followed by Videl not giving up against Spopovich, Goku not finishing Fat Buu and Gohan getting arrogant again (Did Gohan not learn what happened the last time that happened)?

and for 50/50 is Super Buu absorbing Vegito (Super Buu wanted to become stronger by absorbing the strongest fighter which was Vegito; but at the same time he should have known Vegito did that to save his children

None of these are even that dumb.
