Yes. Since all desires are a product of the architecture of the brain, if anyone intelligently designed the brain, they could have simply designed it to only desire doing good. For example, you are free to eat cow dung, yet you never do. Why? Because it's repulsive. The same brain system that makes the prospect of eating dung repulsive could have been wired to make the prospect of sinning repulsive.
Conversely, for example, lust is a very powerful motivator. Sex is very enjoyable, even the prospect of sex is enjoyable, which we know is the product of brain chemistry. So the same brain system that causes our chemical enjoyment of sex and pursuing and thinking about sex (or food or air or other basic drives) could have been wired instead to cause our chemical enjoyment of kindness and honesty. To an extent, it is wired that way, but weakly and imperfectly (with excessive genetic variability, and highly sensitive to the right conditions during child development), owing to the fact that those features of our brain are very new products of evolution, whereas basic urges (like sex and hunger) evolved dozens of millions of years earlier and thus are more thoroughly integrated into our brain.
As a consequence of non-intelligent design, that makes sense. As a consequence of intelligent design, it makes no sense whatever. An intelligent engineer would integrate the pleasure systems reinforcing moral behavior just as thoroughly as basic drives--and would exclude needlessly harmful drives like lust (unless the pursuit of lust, like the pursuit of honesty, would never be regarded as immoral). Thus, people who were better designed, would be more consistently moral, and would enjoy being moral so much they would be much happier people as well.
Someday we will have the technological ability to intelligently design ourselves. Until then, we are clearly not the products of intelligent design, and must cope with our imperfections. Thus, if a god designed us, those imperfections must have been deliberately put there by god (or the causal laws that produced them must have been created by god). There is no other way they could have gotten there.
