Yup, falsity is part of the totality of truth. It's true something is true, and it's true something is false. Living in falsity makes reality that much more false, making truth in totality less true with more falsity pervading. Ignorance is bliss, knowledge is suffering. Belief in falsity as truth is worse I think. Willful ignorance is the main issue with ignorance as evil. We're all ignorant to varying degrees ;)
