Trolley Thought Experiment

I take our my shuriken and kill the lone man on the separate path, then let the trolley hit the other five. I disappear into darkness.


But no, this is a very enticing question. It makes me think of the scene in the old Spider-man film, where he's forced to choose between MJ and the people, and he managed to save both. I'd like to think "change the course, then try to save the last one too" is possible. But I neither know exactly how a trolley works, nor do I have an exact map and time constraint to work with, so I can only assume "it's too late".
