Lyric Interpretation - How Come - Ray Lamontagne

[Robert163]

I said how come the pistol now as profit
The bullet some kind of lord and king
But pain is the only promise that this so called savior is going to bring
Love can be a liar
And justice can be a thief
And freedom can be an empty cup from which everybody want to drink

What does he mean by “and justice can be a thief”
