Honestly, a majority of the reasons you gave aren't antagonistic, they're just mean. Do you know the difference between an antagonist and a villain? (Not trying to be mean. Just asking.)

Mario

 * In Black Yoshi's Money Problem, so what if Mario robbed a gas station with Bowser and lied to Goodman? He didn't oppose any protagonist in the video, so he's not an antagonist.


 * In Mario's Turtle Problem, Mario's the main protagonist of the video, since it's told from his point-of-view. Thus, he cannot be an antagonist in that video, even though he did bad things in that video.


 * In Mario's Valentine's Day Problem, yet again, even if Mario did bad things, he is the main protagonist of the video, so he cannot be an antagonist.


 * In Jeffy's Favorite Song, see above. Besides, he bought Jeffy the phone and technically owns it, so he can do whatever he wants with it.


 * In Happy Halloween, see above. Besides, it was very minor.


 * In Jeffy's New Toy, see above. Also, Rosalina would be the main antagonist of the video, since she terrified Mario throughout the video.

As it will take me a long time to do so, I will not name the other flaws in your list. (No offense.) However, many of them have to do with them being villainous acts, not antagonistic acts.

BTW, Rosalina has opposed Mario many more times than that.
