Huang outlines six common stages that lead up to anger-induced killings: The perpetrator feels threatened. He interprets the threat as provocation or an insult. Both parties push and shove as temperatures escalate. Once onlookers start egging them on, any possible retreat is cut off.
黃富源分析，這類凶殺案的發生基本上有六個步驟：加害人先是感到被威脅，進而將這種威脅解釋為對方的一種挑釁、侮辱行為，兩造當事人互相反擊、逐漸加溫，一旦再有旁觀者加以鼓譟，阻斷了雙方的退路，當事人於是開始暴力推打，最後要不是有一方認輸逃走，後悔莫及的悲劇就發生了。
