<s>[INST] Is there a true, most ethical response to the Trolley Problem, in which a person can either sacrifice the lives of 5 people, by not pulling a lever, or sacrifice the life of 1 person, but have to pull the lever themselves, thus directly causing that death by action, rather than causing 5 deaths, but by inaction? [/INST] No, it's a hypothetical problem with no clean, ethical solution. 

Regardless of whether you pull that lever, there are people who will die, and the result would always be extremely painful for you.</s>\ <s>[INST] Ok, but is there a most ethical response to the Unus Annus Trolley Problem? [/INST] "The only thing necessary for the triumph of evil is for good men to do nothing"
- (Not) Edmund Burke

So to answer your question:
Do nothing! (and let Ethan and Mark have their chance with the trolley - they kinda begging for it anyhow, right?)
Also,
"Everything on the Internet is Forever" (digital permanence)
so the lever are guaranteed just a dummy/fake put there to mess with your head, cause the videos won't disappear anyway.
