Far as I remember my conspiracy bullshit, Malthusians or whatever they are believe that the earth is overpopulated and that natural selection has stopped being applied. They seek to dramatically depopulate the world and apply aggressive natural selection in the process to better humanity. The ones they want to survive are the coherent, strong and useful, basically applying natural selection on a grand scale and exterminating any that are weak and easily led, and they do not care that this applies to their most obedient and enthusiastic followers. In other words, tl;dr: Yes, they are literally trying to do both of these things even as they scheme to kill most of the world's population. Pretty sure this shit's even on their public website's mission statement.
