Here's how the WSJ described the [play leading to Uruguay's victory over Ghana:
It doesn't seem to me that what Suarez did was cheating. He apparently made a very rational assessment of the cost/benefit from breaking a rule and accepting the likely penalty, then decided (correctly) that breaking it was the right thing to do for his team. If soccer fans don't like the way it was done, then they should push for a change in the penalty structure.
Now, maybe it wasn't great sportsmanship, but I certainly wouldn't characterize it as cheating. Anyway, after seeing the acting when a player gets bumped on the leg and then falls down in agony clutching his face and wailing like a schoolgirl, I'm not sure that sportsmanship is a consideration in this game, either.
