“Good” is based upon what is of benefit. What someone wants can form a subjective good concerning that want/desire. And any or all desire can be said to have an abstract good associated.
Is watering a dehydrated plant of benefit to the plant? Must we ask the plant for its subjective intent before we can determine what we should do in order to benefit the plant? We can objectively determine what is of benefit concerning any entity. We can even objectively determine what is of benefit to any chosen want or desire. And when we see that a want is benefited by what is detrimental to its own host-body, we have to choose which one to serve. It is much like kicking one of two people out of the boat because there is only enough food for one.
This situation proposes the exact problem of the locked logic (how does one decide when both directions are exactly equal) and also the problem of insufficient known variables for a set of simultaneous equations. And the solution is simply to focus on the unknown variables, to look for extraneous priorities.
In the case of the desire being contrary to its host body, both the desire and the body have objective benefits or goods. But the logic is locked concerning which to serve. It isn’t an issue of the existence of the objective good, but rather an issue of which to serve, which would be more moral.
Morality is about the interaction between entities such that the greater good is served. When the logic is locked on a local subjective level due to equal opposition, the greater good can be found by raising the scope of the interactions being assessed. Because the two entities are in opposition, a third entity must be considered in order to determine the greater good and the “moral choice to make”. Examples might be; “which has a dependent child”, “which will be able to be better off in the future”, “which is most likely to be of benefit to someone else”, or in a socialist society, “which better serves the state” (which is intentionally used to authorize the state).
So even though the logic is locked by contrary directions of the local good, an increase in scope unlocks the logic to provide an objective good and a moral code; eg. “in the case of divorce, the state is best served if the women gets to keep the pink panties” or “in the case of the baby on the train tracks, which ever is most likely to benefit future anentropic harmony has the priority”.
So regardless of the situation, conflicting goods or not, there is always an objective greater balance of good to be found and upon which to deduce an objective moral code or structure as a basis for subjective amendments.
