Well, there's a difference between doing whatever it takes to win and blatantly cheating the way Erika did in the clip you showed. There's a saying in the sports world that goes something like "You play to win the game." Unfortunately, sometimes when someone plays to win, they are made out to be bad sports, but rarely is it because of blatant cheating - it's usually because the player or team in question is playing in such a way that others find it offensive. Let me give a few examples:
Camping in an FPS game - Yes, it's not quite a physical sport, but it's a strategy that is looked down upon in competitive play; despite the anger it incurs, though, it's still a valid strategy.
Running up the score - The New England Patriots football team in 2008 was well known for running up the score on their opponents, ones that they had soundly beaten. It caused a lot of animosity both from opposing teams and from the general public, but again it was a valid strategy - think about this: In a similar situation a couple weeks ago, the New York Mets baseball team was winning by a large margin over their opponent, but in the later innings their opponents began to close the score gap. In the end, the Mets won but by a much closer margin than they may have, and one of their players was even quoted that at one point in the game where he had a chance to possibly give the Mets a bigger lead, he chose not to because he didn't want to be a bad sport. That type of "sportsmanship" almost cost the Mets their win.
"Excessive" Force - this one is trickier to find a breaking point for; on the one hand, doing whatever it takes to win should mean trying your hardest, but on the other hand you don't want people getting hurt for no reason. Most sports have rules against certain acts of force, but even when someone plays within the rules there is controversy, like in this case: In the 1970 baseball All-Star Game, there was a play at home plate in which Pete Rose (a man infamous for his aggressive baserunning) smashed into the catcher and ended up injuring him; many people were upset at how aggressively Rose tackled the catcher, despite the fact that he did so within the rules of baseball. There was a similar play earlier this year, where Scott Cousins injured Buster Posey in a collision at home plate - again, a legal play. The play isn't an anomaly, it happens on occasion, but injury isn't common, and when it happens people are sure to raise concern. At what point should "sportsmanship" override playing to win?
Okay, so I went on a tangent, but my point is: cheating is not acceptable in any form, but playing to win the game should be more important than sportsmanship in any other case. That's my opinion.
