I think that Scott went into the jungle purely to raise his profile. I had not heard of him until now, and there are probably many others like me. In his interview he came across as humorless, and he will probably remain so.
He knew it didn't really matter, that's why he had no intention of doing any of the trials. He didn't care about winning meals for the camp, yet he complained about being hungry after failing. He doesn't have to care what anyone thinks of him, we know who he is now. He achieved his goal, coward or not. And it will lead to more work/money.
