What about the felony murder rule?

The rule of felony murder is a legal doctrine in some common law jurisdictions that broadens the crime of murder in two ways. First, when an offender kills accidentally or without specific intent to kill in the course of an applicable felony, what might have been manslaughter is escalated to murder.

That is, in countries that have it, if you were attempting to commit a violent felony (like kidnapping), which results in a death, it's upgraded to murder, even if accidental.
