Have you ever noticed that it's easier to go down hill, rather than up? Or that breathing at higher altitudes is harder than at lower ones? Is sitting better than standing? Have you noticed that gravity makes falling down infinitely easier than getting up?
Generally, it is easier to go down and do something bad than it is to elevate yourself and do something good. However, there is one exception.
In water, the tendency is to float up to the surface. Why?
Because, when you're in the presence of a life giving object, elevating is easy and falling is hard. When you are in the presence of God, elevating yourself to love others is easier than falling down to degrade.
