Rape and/or murder (not premeditated) can be the result of a visceral response to an unresolved emotional trigger brought on by interactions with an emotionally intimate human-being in the early life of the perpetrator that remains hidden and unresolved.
Premeditated murder is the result of thought out self-interest of the perpetrator with the underlying unresolved emotional energy driving the behavior.
