Nothing Left

Does the term senseless violence imply that violence ever makes sense?
Where’s the line to cross for justification?
Rules that can be bent, but not broken
If you take ours then we’ll take yours until there’s nothing left
I guess the difference is the victim
I mean, enemy
They’ll never listen
We’ve told them nicely
They’ll never understand where we’re coming from
Maybe they will if they’re looking at a gun
