Why can't lots of people who play Golden Balls, tell the truth?

I can understand why they lie during the game, but today after 'stealing' £61,000 the 'lady' who stole said something along the line, "I'm sorry, I'm very very sorry," If she was really that sorry, all she had to do was share her winnings with the runner up. Why didn't she say the truth, "I am glad to have won all the money." ?


If I was forced to take part in the game, and got to the final, I would tell the other person I was going to steal, and share the winnings with them. I would steal, and if they never stole as well, I would share the money with them.

See one main problem at some point all the contestants lie and once they have done it once everyone thinks I do not trust you. The number of times I have seen one steal from the other but £61.000 that would be a right kick in the bollocks unless you went home with it.
Reply:..and if the other person didn't believe you were really going to share?
Reply:I love golden balls but if I was on the show i would have to steel to because i can't trust anyone.
Reply:Well if you told them you were going to steal, they'd do the obvious thing and steal too, so you both go with nothing!
Reply:I hate that show and every one who lies about sharing the money, are horrible, nasty people who should be truley disgusted with themselves. Frankly, I wouldn't want the whole audience to know I was a spiteful, lying person!
