Sick as it sounds, I have heard discussion that some of these mass shooters consider it a "game". They count points for each kill, and if killed by the cops, they "lose" their points. If they kill themselves, they "keep" their points...
Amazing...
also, that while malls are good for targets, schools are better, because all your targets are locked in!
Such is the world today, it seems.
They kill themselves, in what I think is not cowardice, but the final act of defiance to authority. As they see it.
Today, we are all scientific and rational, and we call it mental illness. In olden times it was called demonic possession. In some ways, I think that still applies...
What ever personal demon(s) drive the mass shooters, it seems that while they are strong enough to make them kill (including themselves, often enough) its not strong enough to make them fight.
We see it time and time again, when the police arrive, or when someone confronts one of these shooters, they give up, or kill themselves.
Have there been any cases of one of these crazies fighting it out until killed or captured? Seriously I can't think of any in recent decades, anyway...
