Hurt no living thing:
Ladybird, nor butterfly,
Nor moth with dusty wing,
Nor cricket chirping cheerily,
Nor grasshopper so light of leap,
Nor dancing gnat, nor beetle fat,
Nor harmless worms that creep.

Christina Rossetti wrote far more complex poems than this short one. She is one of my favourite poets and immensely talented to boot. Now and then she turns from sonnets or devotional poems or whatever she has set her mind on to write simple pieces that resonate because of their apparent simplicity. The one above is surely timeless and worthy of our heeding, especially at a time when brutality is on the rise.
