If the other person tries to pull their lever, beat them to death and unpull it if possible.
If there’s no time to do anything but pull the lever you simply don’t pull it.
Regardless you are on either the path of least harm or justified vengeance. The loved one on the status quo path was killed by the person that put them there, so obviously you’re going to need to keep going on the path of murderous vengeance after that.
Philosophy is easy if you use more justified homicide.
