Rats.

Vile minds under selfless deeds
afraid of losing self-esteem,
mislaid into others' consent
to prevent a shameful present;

Walls built up to hide the fear
of showing what cannot appear;
heart is just too obsolete,
brain makes everything concrete.

And lost in convolutions
of a well-fitting maze,
they still feel no hatred
for their captivity;

guinea pigs educated
eating what's been left over.
They call it moral.

I call it approval.
