There are some lines that we don't cross;
Murder, torture, and threats.
There are some lines that we don't cross,
Because we know it's best.

There are some lines that we will cross,
To protect our loved, our cherished.
There are some lines that we will cross,
Once our hope has perished.

There are some lines that we don't cross,
Because we know their payment.
There are some lines that we don't cross,
As long as we can take it.

There are some lines that we will cross;
Unleashing rage, unyielding wrath.
There are some lines that we will cross,
If we see no other path.

There are some lines we draw ourselves,
To hold the monsters at bay.
There are some lines we erase ourselves,
When we know there's no other way.
