Justice?

From the Tarot Lukumi, Justice; from the Diloggun Oracle, Oturupon (twelve mouths):

When slaves were forcibly brought to other lands, they attempted to guard their faith by syncretizing their gods with Catholic saints. Thus St. Barbara became a stand-in for Shango/Chango. Because of her faith, Barbara was locked in a tower and later beheaded by her father (who was subsequently killed by lightning). It's no wonder that people of Santeria made her story their own - both protectors were fighters against injustice. Yet Oturupon's wisdom can seem slightly contrary:

Ifa: The Orisha state that we must never raise problems or incite conflict. That we must take the time to be sure of our words even before we speak.

Proverb: Do not say the first thing that comes to your mind.

Is it justice to have to be silent or overly cautious to protect yourself? Not in my opinion, but I can see how in some cases that would be the smarter choice.
