Question

Hello Rabbi,
How, in your view, does intention in an action affect its moral judgment, and in what way?
In different cases the intuition seems different. Suppose in case A: a person saves another person from death even though he wants him dead (for example, the rescuer is in a political rivalry with the survivor’s son and simply wants to prevent the son from receiving an inheritance). The action seems morally worthy. On the other hand, case B: a wartime bombing that causes the deaths of innocent people alongside terrorists. It seems that there is a difference in the morality of the action depending on whether the intention was to eliminate the terrorists (and the deaths of the innocent are only a side effect), or whether the intention was the death of innocent people.
 
Thank you in advance
