consider this for example.... you are working as someone who switches the rail tracks from one line to another. An old maintenance guy is working on one of the train lines, and all trains have been diverted from the tunnel he is in. However, you notice that in the other tunnel, where the trains will be going there is a group of 5 children playing. They know they shouldn't be there, but they are playing on the tracks. A train approaches and you notice that you are standing at the switchboard and could divert the train.
Now....would you let the train keep going and kill the 5 children, or would you divert the train and kill the maintenance guy.
this is one example where your actions are determined by consequences rather than right or wrong, because either way, somebody is going to die.
