The Word's Greatest Killer

A dangerous creature with death in it's smile And known to eat humans the adult crocodile Those who swim where they live with death choose to dice Even the thought of such an end to your life is not nice Some times to eat lions and tigers humans do kill Though most man eating big cats known to be old, injured or ill Of creatures of their size respect comes through fear And to them it would be prudent to not venture near Sharks can kill and eat humans especially the great white And some non man eaters such as snakes and spiders have death in their bite But than all of the fore-mentioned one more dangerous that's how it seems to be More dangerous to many and more dangerous to me The World's greatest killer of people of all As in their written history historians do recall Are homo sapiens or better known as human kind To harm or kill their own sort some of them far too inclined.
