instrument of torture

Torture (from the Latin tortus, “twisted") is the act of deliberately inflicting physical or psychological pain on an organism in order to fulfil some desire of the torturer or compel some action from the victim. Torture, by definition, is a knowing and intentional act; deeds which unknowingly or negligently inflict pain without a specific intent to do so are not typically considered torture (though many of the consequences may be the same).
