Trolley problem is a bullshit in the first place, just as your “what if” nonsense. Millions of innocent children are dying and being tortured already by the capitalism, which is also main cause of global warming.

Ok, why is the trolley problem bullshit? Seriously.

Because it implies utilitarianism is the best option by oversimplifying the problem. For example in your example you gave zero details on the situation.

It’s what we call an abstraction.

You people. I swear.

Typically, an abstraction maintains the essence of the original. Asking “what if <good thing>, but it costs <bad thing>” isn’t an abstraction.

I’m not aware of a proposed solution to climate change that involves mass torture or murder.

The question feels more like one of those terrible parlor games where you have to pick a few cards and then argue some randomly generated point.
