Consider who this mentality benefits most. Things are certainly going to get very awful, but as they get worse there will come a time when those most responsible are held accountable, one way or another. The sooner this occurs the more people are likely to survive. Yes, a vast many, maybe even most of us could perish, but retreating into doomerism, choosing to do nothing, means prolonging the worlds destitution by postponing change. Humans, as a collective, are not a species that likes to give up, the sooner we do something the more lives we save, even if it is just a few. I will not blame you for forsaking the collective in order to preserve the individual but pushing that mentality to others could do real harm. The only people who benefit from this choice are those responsible for our doom.
