don't think he’s saying everyone who seeks to be good is evil, only that the face of evil consists in the seeking to be good. Because even if being “good” was going to church, you will have the types that persecute those who don’t go to church. Virtually all evil is in projecting outward your failure to be good, and you only “seek” to be good if you feel you are morally deficient.

I do not think that going to church be default makes you good nor that it isn't requirement for being good but was just an example of how the values of society have shifted.
I also think that all people are morally deficient and should strive to be good but simply that what the world presents to us as the pathway to "goodness" is false.
I am not sure that I understand exactly what you are saying but I do not feel like we disagree.
Perhaps it is something along the lines of "the road to hell is paved with good intentions"
good way to put it — yeah, not implying you were making the point that church = good. Just using your example to show that no matter what = good, it will be not only be inadequate, but the very act of trying to achieve that false sense will also be projected onto others and cause people to persecute them, i.e., be evil.
