An Omnicider is one who has the urge to kill all around them, indiscrimate to the havoc and ruin they cause. This is a fitting term for the Suicide Bombers that seem to be prevalent these days, since that is their ultimate goal: To effect an act of Omnicide
And omnicider detonated themselves today, killing 7 and wounding 10.
