It is all our fault, just not for the reasons you mentioned. It's our fault for allowing it to happen, it's out fault for voting for capitalism, it's our fault for being undereducated, it's our fault for not stopping it. The problem isn't that it's our fault, the problem is that we haven't killed anyone over their exploitation of us and our planet yet, except ourselves.

Society breeds civility through cowardice, we know this because it's immortal to attack a bad actor.
