One of the justifications that psycopaths and sociopaths use is exactly this - If their victims weren't so stupid, they wouldnt be victims. (Often mixed with the "if I didnt exploit them, someone else would"). Its an excuse to rationalise and try to justify their bad behaviour.

NATURAL selection is built to deal with NATURAL problems, and they move and change and evolve at the same speed, natual selection changes at the speed of genetic mutations of large populations, we didnt have smartphones even 1 generation ago - so how the hell is natural selection supposed to adapt to that?

When you have an electronic device thats beaming in risky behaviour at millisecond latency, what's the difference than having a big pile of cocaine in the kitchen and then blaming the addicted person saying "Its just natural selection, that enourmous pile of drugs thats just sitting there - you took it willingly", this is hyperbole but its illustrating my point - immediate availabity of dangerous risky addictive behaviour is a problem that will seduce a lot of people that otherwise would not have had the problem.

Im definitly someone in favor of personal responsibility but "ne quid nimis" and this must be balanced by a strong culture with good leadership to help the people who cant do it by willpower alone, so saying "Its just natural selection" is pure sociopathic / empathy-less answer and is unacceptable in a world where we should be helping and guiding each other and not saying "sounds like a you problem" while cranking up the exploitation dial.
