We have been conditioned to readily accept that the world is teeming with regular people, who have everything to lose but are still psychotic enough to go shoot up school children, knowing full well they will be caught if not killed.
We have been conditioned to readily accept that technology allows any old dude hiding in a cave in the middle east can murder thousands of people tens of thousands of miles away.
We have been conditioned to believe that depressed men collect major arsenals, and can get them past heavy security measures up into hotel rooms and start shooting at gatherings below.
We have been conditioned to fear each other.
If these lone people can be so crazy that they become mass murderers, why can we not extrapolate that persons who will lose NOTHING because they control EVERYTHING are even more likely to murder many millions and are the true psychopaths in this fine world.
