outburst, rave, fret, force, violence, cruelty, outrage
暴 centers on uncontrolled, forceful energy breaking out: an outburst of emotion, violent action, or cruel force. The idea of raving or fretting is a natural extension of that loss of control.
暴 originally depicted a person exposing something to the sun, later associated with violence and outbursts. The modern form combines 日 (sun) with a lower component that historically represented exposure or drying, but the exact development is uncertain.
The sun 日 blazes down on the lower shape 㳟, which looks like a person with arms raised in a frenzy. Imagine the heat driving someone into a violent outburst.
For ボウ, picture a sudden outburst like a bow (as in bow and arrow) snapping: the sharp sound 'bow' cues ボウ, and the violent release matches the kanji's meaning.
