"Justice" is just a stat. When a weapon has a mod with +1 Justice, any affinity it gains charges up a gauge in the bottom right hand corner of the screen. After around 2000 affinity, it fills the gauge and you unleash AoE damage around you. Justice does Fire. It also restores 25% of your health, and does some sort of other buff.

All other Syndicates have similar 'stats', and do different damage, restore different stats (energy, health and shields) and different buffs.
