Technically, field players cannot use the hands, so it could be considered cheating. However, there is a punishment for that and is straight red card (which enables the discipline table to suspend the player for more than one match, contrary to double yellow card which is only one match).
So, it is the last minute of the second extra time, the ball comes straight to you. If it scores, there is no way to recover (only a penalty kick can be executed after the time ends). Your goalkeeper has been beaten, and if you lose, you are out of the Cup. If you block it with your hands, you are expelled, and they get a penalty. There is the possibility of your goalkeeper catching it (or the executor missing the mark), which would allow your team to go to penalty kicks. But even if your team wins, there is a good chance of being suspended for one or two matches, which would be goodbye to the World Cup. There is nothing bigger for a soccer player than the final match of a World Cup, and Uruguay hasn't been there in 50 years.
What would you do?
From a South American perspective, if you doubt, you don't belong to the national team. The team is first and foremost, no matter if it means you will be watching the final match with the audience.
As mentioned before, it happens in every sport. Don't basketball players make faults when a member of the other team is running alone to score? Do they all end the game with 0 faults? No, they know they can commit 5 or 6 faults, so they use them to benefit the team. In soccer there is no goal tending (or penalty try as in rugby). To score the ball must cross the line, it is this simple. Giving a goal and expelling a player for doing this would be an exaggerated punishment (for example, a player punching an opponent to death in the midfield would be punished only with expulsion, but not with a goal).
Most of the times these matches end with a team with one less player and losing the game because the opponent scores. Ghana had its opportunity and missed it. In the World Cup, there is a line which divides teams between those that are prepared for the glory and those that must walk away and try again in the future.

That said, people don't forget and karma's a bitch - I can see Worstguay losing by a similar contentious decision next game.
I doubt it. However, they managed to get the English referee replaced because they feared an English referee would bring problems after what the Uruguayan referee did to England.
Besides, if Netherlands/Holland/Lowlands/How_many_names_you_got? does something similar, I have no doubt Uruguay would score the penalty.
