I'll put it this way.
When Todd convinced James he was safe, James committed a dumb move - he didn't play one of his two idols. What did the tribe do in response? Just vote him off.
When the Black Widows convinced Erik to give up immunity, Erik committed a dumb move - he handed over immunity to Natalie. What did the tribe do in response? Just vote him off.
When Russell convinced J.T. that there was a female alliance on the Villains camp, J.T. committed a dumb move - he passed his idol to Russell. What did the tribe do in response? Russell handed the idol to Parvati, who passed an idol to Sandra and another to Jerri, which nullified the Heroes' votes, and as a result, a 5-5 vote was rendered null and void.
It took a much better move to get rid of J.T. than it did to get rid of James and Erik.
