There seems to be a common mania state of irrational exuberance with unrealistic hopefulness. It has many examples: people in love, positive/devout Christians, big-idea startup startup and even residents of Raqqa under the Islamic State playing in the river Tigris, unreasonably hopeful about their future.
To bring the point home, unrealistic hopefulness or hopelessness sets a person up for failure. Whether they internalize any resulting failures into bitter anomie and desire for omni/suicide depends on an individual's coping skills, ideology and social support (or lack of each thereof). Combine a lack of hope, opportunities and many negative experiences leads to angry people who take their pain and loneliness, and wish to lash out.
