Woo feeds on fear, and fundies invented fictional places like Hell to strengthen its grip. Pascal's Wager is a blatant, transparent appeal to cowardice. Instead of being allowed to suspend judgment until the evidence comes in, the concept of Hell exists to frighten us into rushing into an unwarranted conclusion.
It takes courage to be a skeptic: Uncertainty is something we face all the time. we know that we could be wrong about pretty much anything, and that if the right evidence comes in tomorrow, we'll have to change our minds. There is also so much we don't know about the universe, yet.
Fundamentalists take the coward's way out: Faith. They paint pretty (to them) pictures over the unknown, as well as over the evidence that doesn't fit in with their comforting beliefs. For those who invoke Pascal's Wager, it's even more blatant: They don't believe because of anything like evidence, but because they fear something their predecessors invented without evidence to keep them in line. Morally speaking, they're pitiful creatures who act not out of love or compassion but fear of arbitrary punishment and/or greed for equally arbitrary rewards. Instead of risking their comfort by standing up for justice or truth, they're only looking out for themselves.
