My comrade. My sweet, caring comrade.

Even if you are close to the switch, the switch is a diversion. The trolley is moving forward with kinetic energy KE that will be partly dissipated as it crushes bodies. You did not push the trolley to reach that level of energy, and more importantly, nor did you tie those people to the tracks. Everything happens for a long chain of reasons, some more influential or determinative or culpable than others. In the trolley problem the main guilty party is the one that tied the people to the tracks, or made sure that the trolley would be on track to kill people, or didn't have a functional onboard hazard-detection mechanism, etc. In the drowning child scenario there is someone who either put the child in danger or let them become endangered. In the global reality there are people who are too poor to afford bednets.

Whenever we are put in a reductive quandary where we have to choose between two evils, we must see the power forcing us into that situation as the evil that is to be resisted.

We have a large amount of control over what we directly experience in our own lives and a small amount of control over what we are indirectly connected to. I hope you are able to see yourself as a good person after reading this, because I do.
