The fearful are often holders of the most dangerous power. They become demoniac when they see the workings of all life around them. Seeing the strengths as well as the weakness, they fasten only on the weakness.

Vengence is in my heart, death in my hands, blood and revenge are hammering my head.
-Titus Andronicus, Act II, sc. 3, 1. 38

The sword is ever suspended.
-Voltaire

Setbacks aren't failures, only battle scars that make you stronger.
