They had them figured out to the penny, and as you say, the trolls do that to. To them, it must mean to kill the weak saves them money. How nice.
That is the logic of all forms of socialism. Everybody puts their labor into the common pot. Everbody takes their living out of the common pot. Therefore, we all have an interest in what everyone else contributes. We all become busybodies. It is plain good sense and rational for the more productive/stronger half to kill the weaker half who don't contribute their share. Then there will be more for everybody -- everybody who survives, that is. The logic is irrefutable if you have no moral law. Socialists recognize no moral law.
And once the weaker half are killed off, the same logic applies again -- kill the underproductive! In the end, I suppose it would get down to two socialists, with one socialist killing off the other.
I wish to remind our socialist friends, the cure for this lunacy is free market economics and moral law.
