Deep Scars

Histories of the past prove
Bio weapons's horror
Powerfull, severe threat, hardly to see
Quick effect, murder fast, pain is what they feel

2 millon years in progress
They're still creating new weapons
Instead of find the cancer's cure
Forever deep scars

Malevolent science
Humankind's sacrifice
Bio arm in the environment had been use before
Tragedy, experiment, we ask never more
