It's all about a shame-based society. When someone is made to feel ashamed, they might lash out. It's practically the opposite of guilt, which is directed inwardly.
At the margins, a shamed person might commit mass murder, while a guilty person might commit suicide.
Before you get to the margin, both guilty people and shamed people might alter their behavior in beneficial ways, but they do it for subtly different reasons.
