Virus

Replicate, divide, mutate, survive

Tame? Beat. You hungry? Control tastes so sweet

Species? Walk tall. Now show me the difference so small

Kill, eat, exploit the weak

It's freedom? That's choice. You listen because I hear no voice

Tested, still lives? Now tell me the strong will survive

Kill, eat, exploit the weak

(Can't build a chain from missing links.)
