I was thinking that myself after the Exile's predicament was revealed. The "Zero To Hero" approach makes sense given that the game is based of the D&D rules system, but it makes no sense to anyone who follows the Star Wars Universe. The Dark Side is supposed to be the quick and easy path.
As for Handel's moral problem, I find it no problem to play Light Side. You just have to be a good person who seeks to aid others. Given that my coffers and inventory were overflowing with more stuff that I could reasonably use ina game, I had no problem turning down a poor peasant's 200 credit reward.
The Jedi Masters in the game are supposed to be wrong, and are probably closer to the Dark Side than they realise. The arrogance and self-righteousness of the Jedi Order is a recurring theme in SW fiction, including the prequel movies. But that doesn't mean the Jedi Code itself isn't a good example of how to follow the Light Side: seek to prevent the loss of life whenever possible, don't give into fear or agression, and try to understand why people are acting as they are and where possible, redeem them.
