If we both are on a cliff face and you fell off, and now you are dangling connected by rope to only me. Standard movie trope.
Now because of your weight my only options are to cut the rope - you die, or wait and we both die. This is more accurate example we are talking about here, not killing poor people because 'crime'.
Also I would like to point out that poor people are not root cause of crime. So you are not tackling actual problem, only applying band-aid solutions. But that's a tangential topic.
Neither is climate change, is it? Unless there's some research I haven't heard about, I think you're doing science denial misinformation spouting.
At this stage this is trolling.
There is too big of an asymmetry with the current situation: profits, tax incentives, lobbying, and regulatory capture. This is not something that the average person can address from within the existing judiciary system.
At the moment you will need either something that will make carbon emissions unprofitable, or an epiphany from those abusing the status quo, that would lead to de facto climate regulation. Neither of those will happen without some incentive (positive or negative).
