Can Kantian Maxims have more than one goal? Suppose I tell the murderer at the door that my mother is not home in order to save her life. That itself may be fine, but equally I am saying that in order to deceive him, and so may have an obligation not to.
All the example maxims I have seen have involved one reason to perform one action.
The trolley example is similar. This time, it is prohibited because the maxim should be phrased as "murdering one person to save five". But why can't I just phrase it as "diverting a run away trolley away from five people to save their lives".
Is the idea that we have to think of our maixm in the worst way possible, then try and universalise it? Then why isn't telling the truth prohibited by bringing about a murder? After-all, it is not my desired goal to kill the one person.
The obvious answer is you phrase your own action and agency in the worst possible way and the goal and motive in the best. So
- lying to save a life
- murdering someone to save five people
But it seems too obvious and unstated.
