The Article presents findings from the first systematic study of intim
ate homicide cases that raise the heat of passion or provocation defen
se. Based on this data, it argues that legal reform has shaped a flawe
d image of passionate killing, an image that ignores, and thus partial
ly punishes, women's attempts to separate or depart from intimate rela
tionships. After examining the standard theories of self-control suppo
rting reform's approach, the Article argues that the provocation defen
se, in practice, protects something more than the defendant's autonomy
. It protects norms about relationships. We have not recognized this,
the Article argues, because reform has transformed all of the normativ
e questions into questions about reasonable persons, an intellectual s
trategy that has kept the law standing still in the face of social cha
nge and has led feminists and liberals to talk past each other. Finall
y, this Article tackles one of the oldest and most fundamental questio
ns about the provocation defense-why it is that the law protects passi
on at all-and proposes an answer that seeks to free the law of murder
from the veil of relationship at the same time as it acknowledges that
there are some passions the law must continue to protect.
