One kills a man, one is an assassin; one kills millions, one is a conqueror; one kills everybody, one is a god.

A sword never kills anybody; it's a tool in the killer's hand.

It hath the primal eldest curse upon't, A brother's murder!

There is no sure foundation set on blood, No certain life achieved by others' death.

He who bears the brand of Cain shall rule the earth.

It is long and hard and painful to create life: it is short and easy to steal the life others have made.

No humane being, past the thoughtless age of boyhood, will wantonly murder any creature which holds its life by the same tenure that he does.

It is forbidden to kill; therefore all murderers are punished who kill not in large companies, and to the sound of trumpets.

A man's head is not like a scallion, which will grow again if you cut it off; if you cut it off wrongly, then even if you want to correct your error, there is no way of doing it.
