A common theme of adventures, especially high fantasy type adventures so prevalent in Pathfinder and other TTRPGs is fighting against, and eventually overcoming, injustices. I am happy to see Paizo taking a strong stand, at least verbally, with this announcement and I am cautiously optimistic with regards to how the upcoming AP books will be handled.
“I do not pretend to understand the moral universe. The arc is a long one. My eye reaches but little ways. I cannot calculate the curve and complete the figure by experience of sight. I can divine it by conscience. And from what I see I am sure it bends toward justice.”
-Theodore Parker (1853)
